  • Focused, titrated buffer stocks for crystal screening, optimization, & production
  • 用于晶体筛选、优化和生产的集中滴定缓冲液

描述

StockOptions Buffer kits are reagent toolboxes for the macromolecular crystal grower. Stock-Options reagent kits offer precisely formulated, high quality crystallization grade reagent stocks in convenient, cost-effective kits. The chemicals utilized in StockOptions kits are the same crystallization grade, ultra-high purity chemicals utilized in the Hampton Research kits. StockOptions reagents are carefully formulated under strict quality standards to ensure reliable performance and lot-to-lot consistency.

Preformulated stocks remove calculation, measurement, and formulation errors. No more second guessing how the reagent was formulated, what specific chemical was used, when it was made, or how to precisely reproduce that reagent when it is gone and more reagent is required for additional setups.

Each HR2-233 contains 21 unique reagents covering the pH range of 3.6 to 5.6 in 0.1 pH increments. Each reagent is supplied in a 10 milliliter volume and is titrated using HCl.

StockOptions 缓冲液试剂盒是大分子晶体生长器的试剂工具箱。 Stock-Options 试剂盒以方便、经济高效的试剂盒形式提供精确配制的高质量结晶级试剂库存。 StockOptions 套件中使用的化学品与 Hampton Research 套件中使用的结晶级超高纯度化学品相同。 StockOptions 试剂按照严格的质量标准精心配制,以确保可靠的性能和批次间的一致性。

预先配制的库存消除了计算、测量和配方错误。 无需再猜测试剂是如何配制的、使用了何种特定化学品、何时制造,或者在试剂消失后如何精确复制该试剂,并且需要更多试剂来进行额外设置。

每个 HR2-233 包含 21 种独特的试剂,涵盖 3.6 至 5.6 的 pH 范围,以 0.1 pH 为增量。 每种试剂的容量为 10 毫升,并使用 HCl 进行滴定。

应用

  • Oil based cryoprotectant

特征

  • Synonyms used in the crystallographic literature: Paratone® N, Paratone® 8277, Infineum V8512
  • Oil based cryoprotectant

描述

Sorry, Parabar 10312 is no longer available.  We’ve left this page up for reference only.  See HR2-861 Santovac Cryo Oil as a possible substitute.

抱歉,Parabar 10312 不再可用。 我们保留此页面仅供参考。 请参阅 HR2-861 Santovac Cryo Oil 作为可能的替代品。

Parabar 10312 is a viscous cryoprotectant for both small and large molecule crystallography.1

Mildly air-unstable, small molecule compounds can be coated with Parabar under an inert atmosphere. The Parabar protected crystal sample can be cryocooled in a chilled nitrogen gas stream. Parabar has also been used successfully as a cryoprotectant for biological macromolecule crystals. 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 Parabar can minimize evaporation from the crystal and reduce exposure and slow diffusion of air (oxygen) to the crystal.

HR2-643 Parabar 10312 is no longer available and has been discontinued effective May 11, 2021.

HR2-862 Parabar 10312 is supplied as 5 ml in an amber glass vial with glass applicator rod in screw cap lid.

The viscosity of Parabar can be reduced to improve handling with fragile needle and blade crystals by mixing 50:50 with Paraffin Oil.

Parabar is a blend of polyisobutylenes with a Staudinger molecular weight of about 20,000 and contains about 20% polymer.

Refractive index 1.48487 at 20°C.

Parabar 10312 是一种粘性冷冻保护剂,适用于小分子和大分子晶体学。 1

可以在惰性气氛下用 Parabar 包覆对空气轻微不稳定的小分子化合物。 Parabar 保护的晶体样品可以在冷冻氮气流中进行低温冷却。 Parabar 也已成功用作生物大分子晶体的冷冻保护剂。在晶体安装在低温回路中后,在低温晶体学期间用于置换和减少晶体上的水(母液、试剂)量。用 Parabar 涂覆晶体可以最大限度地减少晶体的蒸发,并减少空气(氧气)向晶体的暴露和缓慢扩散。

HR2-643 Parabar 10312 不再可用,自 2021 年 5 月 11 日起停产。

HR2-862 Parabar 10312 以 5 ml 装在琥珀色玻璃小瓶中,螺旋盖盖中带有玻璃涂抹棒。

通过将 50:50 与石蜡油混合,可以降低 Parabar 的粘度,以改善易碎针状和刀片状晶体的处理。

Parabar 是聚异丁烯的混合物,Staudinger 分子量约为 20,000,含有约 20% 的聚合物。

20°C 时的折射率为 1.48487。

100°C 时运动粘度为 641 cSt。 100°C 时运动粘度比为 2.05。

清晰到略微朦胧的是外观。

晶体学文献中使用的同义词:Paratone® N、Paratone® 8277、润英联 V8512。

描述

Citrate BIS-TRIS propane (CBTP) is a buffer system useful across pH 2.5 to 9.5.

Using CBTP one can use a single buffer system to screen pH 2.5 to 9.5 by varying the ratio of Citric acid to BIS-TRIS propane. Although the two buffer reagents are made available separately for convenient, individual replacement, they are designed to be used together, with the supplied CBTP buffer titration table to create a crystallization buffer system covering pH 2.5 to 9.5.

柠檬酸盐 BIS-TRIS 丙烷 (CBTP) 是一种适用于 pH 2.5 至 9.5 的缓冲系统。

使用 CBTP,可以使用单一缓冲系统通过改变柠檬酸与 BIS-TRIS 丙烷的比例来筛选 pH 2.5 至 9.5。 虽然这两种缓冲试剂是分开提供的,以便于单独更换,但它们被设计为一起使用,与提供的 CBTP 缓冲液滴定表一起创建一个涵盖 pH 2.5 至 9.5 的结晶缓冲系统。

应用

  • Crystallization grade NDSB-211 for formulating screens or for optimization
  • 结晶级 NDSB-211 用于配制筛选或优化

特征

  • Efficiently solubilizes proteins at non-denaturing concentrations
  • Useful in preventing protein aggregation
  • Non detergent sulfobetaines (NDSB) are used for protein folding, renaturation and crystallization
  • Protein specific additive for solubility and stability
  • 在非变性浓度下有效溶解蛋白质
    可用于防止蛋白质聚集
    非洗涤剂磺基甜菜碱 (NDSB) 用于蛋白质折叠、复性和结晶
    用于溶解性和稳定性的蛋白质特定添加剂

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.

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涵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。

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