描述

Used during cryocrystallography to displace and reduce the amount of water (mother liquor, reagent) on the crystal after the crystal is mounted in a cryoloop. Coating the crystal with oil can minimize evaporation from the crystal and reduce exposure and slow diffusion of air (oxygen) to the crystal.

Santovac Cryo Oil offers low viscosity, incredibly low vapor pressure, low surface tension, excellent chemical inertness and excellent thermal stability.

Dip the mounted crystal into the oil to displace surface water. Or add a small amount of Santovac to the crystallization drop before mounting the crystal. After adding the Santovac, mount the crystal using a Mounted Cryoloop. Withdraw the mounted crystal from the drop and the Santovac will coat the mounted crystal. Cryogenically cool the mounted crystal.

Santovac (Santovac 5) is a five ring polyphenyl ether (PPE) with very low vapor pressure and low reactivity. The oil is highly resistant to oxidation. The only elements in the pure polyphenyl ether are oxygen, hydrogen and carbon.

The fluid is chemically stable, non-corrosive, safe and non-toxic at normal operating temperatures.

Santovac is not miscible with water, paraffin oil, silicon oil, alkanes, or Parabar 10312 (Paratone). Santovac is miscible with acetone. Shelf life 5 years.

描述

The NDSB are a group of zwitterionic compounds that can reduce aggregation and aid in refolding proteins found in inclusion bodies and bacterial expression systems.

Non detergent sulfobetaines have a sulfobetaine hydrophilic group and a short hydrophobic group that cannot aggregate to form micelles, therefore NDSB’s are not considered detergents. NDSB increase the extraction yield (up to 30%) of membrane, nuclear and cyto-skeletal associated proteins. The short hydrophobic groups combined with the charge neutralization of the sulfobetaine group results in higher yields of membrane proteins. NDSB have been used in refolding and renaturation of chemically and thermally denatured proteins.

The non detergent sulfobetaines are zwitterionic over a wide pH range, easily removed by dialysis and do not absorb significantly in the near UV range.

Typical useful NDSB concentration in protein sample is 0.5-1.0 M.

NDSB 是一组两性离子化合物，可以减少聚集并帮助重新折叠包含体和细菌表达系统中发现的蛋白质。

非洗涤剂磺基甜菜碱有一个磺基甜菜碱亲水基团和一个不能聚集形成胶束的短疏水基团，因此 NDSB 不被视为洗涤剂。 NDSB 可提高膜、核和细胞骨架相关蛋白的提取率（高达 30%）。短疏水基团与磺基甜菜碱基团的电荷中和相结合，导致膜蛋白产量更高。 NDSB 已用于化学和热变性蛋白质的重折叠和复性。

非去污剂磺基甜菜碱在很宽的 pH 值范围内是两性离子的，很容易通过透析去除，并且在近紫外范围内不会显着吸收。

蛋白质样品中典型的有用 NDSB 浓度为 0.5-1.0 M。

描述

Mounted CryoLoops with 10 micron diameter nylon. The 10 micron Mounted CryoLoop shows less background diffraction than the 20 micron Mounted CryoLoop. Please note that the 10 micron Mounted CryoLoops are very flexible due to their small diameter. These nylon loops are bonded to hollow, stainless steel MicroTubes™ that are used to mount, freeze, and secure the crystal during cryocrystallographic procedures and X-ray data collection. The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and secure to the CrystalCap using epoxy or similar adhesive. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.

Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicroTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.

安装有 10 微米直径尼龙的 CryoLoops。 10 微米安装的 CryoLoop 显示的背景衍射比 20 微米安装的 CryoLoop 少。请注意，10 微米安装的 CryoLoop 因其小直径而非常灵活。这些尼龙环与中空不锈钢 MicroTubes™ 粘合，用于在低温晶体学程序和 X 射线数据收集过程中安装、冷冻和固定晶体。 MicroTube 的长度为 24 毫米，专门设计了 10、12、14、18 和 21 毫米尺寸的 EasySnap™ 凹槽。要获得所需长度的 MicroTube，只需将 MicroTube 卡入所需长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。这些尼龙环显示出最小的衍射，很薄，可以快速冷冻，坚固且符合空气动力学。

大多数数据收集几何结构更喜欢或要求帽底和梁之间有 22 毫米的长度。对于使用 CrystalCap、CrystalCap ALS、CrystalCap ALS HT 和 CrystalCap SPINE HT 的 22 mm 总长度，将 MicroTube 从底部的第二个凹口处卡入，形成 18 mm 的 MicroTube 长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。对于 22 mm 以上的长度，使用 CrystalCap Copper、CrystalCap Copper HT、CrystalCap ALS Copper HT 将 MicroTube 卡在从底部算起的第五个槽口（最靠近 CryoLoop 的槽口），并使用环氧树脂或类似粘合剂固定到 CrystalCap。

描述

Similar to the Mounted CryoLoop™ in design and function, the Adjustable Mounted CryoLoop allows one to manipulate and orient the CryoLoop to multiple, unique positions previously unattainable with typical cryo setups. The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.

Using forceps or a probe one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.

The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and stake it to the CrystalCap™ Magnetic or CrystalCap™ Copper Magnetic. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.

在设计和功能上与 Mounted CryoLoop™ 类似，可调节的 Mounted CryoLoop 允许人们操纵 CryoLoop 并将其定位到多个独特的位置，这些位置以前是典型的低温设置无法达到的。可调节安装的 CryoLoop 是一个直径 20 微米的合成环，安装在可延展的不锈钢套管内，而不锈钢套管又安装在 EasySnap MicroTube™ 内。

使用镊子或探针可以通过弯曲和调整固定 CryoLoop 的可延展不锈钢插件的角度来控制 CryoLoop 的角度和方向。可调节安装的 CryoLoop 可以多次定位。注意：重复操作会使套筒疲劳，从而导致套筒失效。可调节安装的 CryoLoop 设计用于与 CrystalCap 系统组件一起使用。

MicroTube 的长度为 24 毫米，专门设计了 10、12、14、18 和 21 毫米尺寸的 EasySnap™ 凹槽。要获得所需长度的 MicroTube，只需将 MicroTube 卡入所需长度并将其固定在 CrystalCap™ Magnetic 或 CrystalCap™ Copper Magnetic 上。这些尼龙环显示出最小的衍射，很薄，可以快速冷冻，坚固且符合空气动力学。

Products > Crystallization Plates, Hardware & Accessories > Dialysis Buttons, Membranes & Applicators > Dialysis Buttons

Dialysis Buttons

应用

Crystallization by dialysis, protein folding, & small volume sample dialysis
通过透析、蛋白质折叠和小体积样品透析进行结晶

特征

Low volume dialysis
Fits in 24 well plates
Use over and over again
低容量透析
适合 24 孔板
反复使用

描述

In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.^1-3

Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.

在透析方法中，有问题的样品通过半透膜与“沉淀剂”分离，半透膜允许小试剂分子通过，但阻止生物大分子穿过膜。1-3

透析按钮由聚苯乙烯注塑成型，大小与小按钮相当。将样品放置在该腔室中，以便在按钮顶部形成一个轻微的液体圆顶。透析膜放置在按钮/样品的顶部，并用 O 形环固定到位。 O 形环由透析按钮中的凹槽固定到位。透析按钮配有 O 形圈。 5 µl 至 100 µl 大小的透析按钮的总高度约为 6 mm，外径约为 10 mm，未安装 O 形圈，直径约为 12 mm，安装了 O 形圈。 200 µl 和 350 µl 大小的透析按钮总高度约为 8 mm，外径约为 15 mm，不带 O 形圈，直径约为 17 mm，带 O 形圈。每个透析按钮包都包括一个塑料高尔夫球 T 形涂抹器，以帮助将透析膜应用到按钮上并使用随附的 O 形圈固定。

描述

Micro-Bridges are small devices in the shape of a bridge that are designed to carry out sitting drop vapor diffusion crystallization when placed in a VDX™ Plate or Linbro® Plate. A single Micro-Bridge fits neatly into the reservoir of a standard 24 well VDX Plate for a sitting drop crystallization experiment. Once placed inside the wells, Micro-Bridges are stable and there is no need to stick them to the wells with grease or adhesive. It is therefore possible to transfer them to other wells during or after a crystallization experiment.

Why sitting drop? Placing the droplet in the indentation greatly reduces the risk of losing the protein by accident. Crystallization can be carried out in the presence of detergents and organic solvents which are compatible with polystyrene (such as MPD, iso-propanol, and ethanol). The protein drop is less affected by condensation problems. Soaking and seeding experiments can be carried out easily. Crystals can be transported more securely. Larger drop volumes can be used. Micro-Bridges have a concave indentation in the top surface of the bridge which holds the sample droplet during a crystallization experiment and prevents the droplet from spreading over a large area. Made from polystyrene, these parts are highly transparent and suitable for most crystallizations. The surface of the indentation is highly polished to facilitate the visual inspection of the drops under a microscope. The maximum drop volume for the Micro-Bridge is 35 µl. Reservoirs can be sealed with plain cover slides and vacuum grease or clear sealing tape.

微桥是桥形的小型设备，设计用于在放置在 VDX™ 板或 Linbro® 板中时进行坐滴蒸汽扩散结晶。单个 Micro-Bridge 可巧妙地装入标准 24 孔 VDX 板的储液器中，用于坐滴结晶实验。一旦放置在孔内，Micro-Bridges 就很稳定，无需用油脂或粘合剂将它们粘在孔上。因此，可以在结晶实验期间或之后将它们转移到其他孔中。

为什么要坐下来？将液滴放入压痕中可大大降低意外丢失蛋白质的风险。可以在与聚苯乙烯相容的去污剂和有机溶剂（如 MPD、异丙醇和乙醇）存在下进行结晶。蛋白质下降受冷凝问题的影响较小。可以轻松进行浸泡和播种实验。水晶可以更安全地运输。可以使用更大的液滴体积。微桥在桥的顶部表面有一个凹形压痕，用于在结晶实验期间固定样品液滴并防止液滴在大面积上扩散。这些部件由聚苯乙烯制成，高度透明，适用于大多数结晶。压痕表面经过高度抛光，便于在显微镜下目视检查液滴。 Micro-Bridge 的最大滴体积为 35 µl。可以使用普通盖玻片和真空润滑脂或透明密封胶带密封储液罐。

描述

These small (25 mm x 25 mm x 0.65 mm) cutting stones are used to make clean cuts of glass and quartz capillaries. Use the edge of the stone to etch the capillary then gently snap the capillary in two. This is useful for cutting the tips off closed capillaries used for mounting single crystals for x-ray diffraction analysis or for cutting capillaries to the desired length.

Capillary Cutting Procedure

1. Gently place the capillary on a clean, flat surface.
2. Gently holding the stone at approximately 30° angle to the capillary tube, starting near one edge of the stone, proceeding in a single, smooth motion, draw the length of the non-serrated edge of the stone across the capillary one time . Apply just enough pressure to score the capillary, do not attempt to cut through the capillary.
3. Pull the capillary axially until it breaks. If it won’t break, the score was not deep enough. Repeat the above steps, pressing down with slightly more force while drawing the cleaving stone the capillary.
4. Once cut, inspect the end finish to ensure the cut quality meets the application requirements.

这些小的（25 毫米 x 25 毫米 x 0.65 毫米）切割石用于对玻璃和石英毛细管进行干净的切割。使用石头的边缘蚀刻毛细管，然后轻轻地将毛细管一分为二。这对于切割封闭毛细管的尖端非常有用，这些封闭毛细管用于安装单晶以进行 X 射线衍射分析或将毛细管切割成所需的长度。

毛细管切割程序

1. 轻轻地将毛细管放在干净、平坦的表面上。
2. 以与毛细管成约 30° 角的方式轻轻握住石头，从靠近石头的一个边缘开始，以单一、平滑的动作进行，将石头的非锯齿边缘的长度拉过毛细管一次。施加足够的压力来刻划毛细管，不要试图切穿毛细管。
3. 轴向拉动毛细管直至其断裂。如果它不会打破，那么分数还不够深。重复上述步骤，在将切割石拉入毛细管的同时稍微用力向下按压。
4. 切割后，检查端部光洁度，确保切割质量符合应用要求。
