描述

The Sodium malonate offered by Hampton Research is Malonic acid (CAS Number 141-82-2) titrated to pH 4.0-8.0 using Sodium hydroxide as described in the publication “A comparison of salts for the crystallization of macromolecules. Alexander McPherson. Protein Science (2001), 10:418-422.”. In this same publication, Sodium malonate was reported to be more successful than any other salt, resulting in the crystallization of 19 of the 23 macromolecules, almost twice as effective as the next most successful salt, which was a draw between sodium acetate, sodium tartrate, sodium formate, and ammonium sulfate. The high success rate of Sodium malonate in producing crystals was even more impressive when an overall unique success rate with individual macromolecules was considered.

The use of Sodium malonate in place of Ammonium sulfate has been reported in one instance to improve the reproducibility of crystals and improve resistance to physicochemical shocks. Sodium malonate also acted as a good cryoprotectant (Xing and Xu 2003).

One may combine the four different sodium malonate stocks to create a pH versus sodium malonate concentration grid for screening or optimization. Refer to the pH/Dilution Table for Sodium malonate.

Based on the structure of malonic acid titrated with sodium hydroxide, there are no chiral carbons so it is not characterized as having enantiomeric structures, such as D or L.

Hampton Research 提供的丙二酸钠是使用氢氧化钠滴定至 pH 4.0-8.0 的丙二酸（CAS 编号 141-82-2），如出版物“用于大分子结晶的盐的比较。Alexander McPherson。蛋白质科学（ 2001), 10:418-422”。在同一份出版物中，据报道丙二酸钠比任何其他盐更成功，导致 23 种大分子中的 19 种结晶，几乎是下一个最成功的盐的两倍，后者是乙酸钠和酒石酸钠之间的抽吸、甲酸钠和硫酸铵。当考虑到单个大分子的整体独特成功率时，丙二酸钠在生产晶体中的高成功率更加令人印象深刻。

据报道，在一个实例中使用丙二酸钠代替硫酸铵可提高晶体的再现性并提高对物理化学冲击的抵抗力。丙二酸钠也是一种很好的冷冻保护剂（Xing and Xu 2003）。

可以将四种不同的丙二酸钠库存组合起来，以创建一个 pH 值与丙二酸钠浓度网格，以进行筛选或优化。请参阅丙二酸钠的 pH/稀释表。

根据用氢氧化钠滴定的丙二酸的结构，没有手性碳，因此不具有对映异构体结构的特征，例如 D 或 L。

1.0 M Sodium phosphate dibasic dihydrate is completely soluble in water at 4 degrees Celsius and higher temperatures. Below 4 degrees Celsius 1.0 M Sodium phosphate dibasic dihydrate will crystallize out of solution. If this happens, warm the reagent at 37 degrees until complete solubility is observed (4 to 8 hours) and then store the reagent between 4 and 25 degrees Celsius.

描述

The Quik Optimize reagent set is designed to deliver a flexible phosphate reagent based solubility and crystallization screening method for the crystallization of biological macromolecules. Quick Optimize allows convenient and simple reproduction of original Quik Screen conditions. The kit is especially useful for refinement and optimization of preliminary successful crystallization conditions determined using Quik Screen.

Quik Optimize is composed of two high purity, sterile filtered stock solutions, 4.0 M Sodium phosphate monobasic monohydrate (NaH₂PO₄ M_r 137.99 CAS Number [10049-21-5]) and 4.0 M Potassium phosphate dibasic (K₂HPO₄ M_r 174.18 CAS Number [7758-11-4]) formulated using ultra pure water. Final reagent pH is determined by the ratio of Sodium and Potassium phosphate reagents. The supplied dilution table makes concentration and pH determinations quick and simple. Reagent concentrations between 0.2 and 4.0 M in 0.2 M increments and pH values between 5.0 and 8.2 in 0.2 pH increments can be conveniently formulated with Quik Optimize.

The Quik Optimize formulation has been used successfully in both crystallographic and bioseparation applications for the crystallization of biological macromolecules 1-7. The phosphate reagent system in Quik Optimize is a stable, flexible, easy to reproduce, cost-effective, and simple way to screen and optimize crystallization conditions for biological macromolecules. Quik Optimize was developed by Macrocrystal Oy and is manufactured and distributed exclusively by Hampton Research.

Each Quik Optimize kit contains 4.0 M Sodium phosphate monobasic monohydrate and 4.0 M Potassium phosphate dibasic reagents, 100 ml each. These ready to use reagents are formulated using high purity salts with ultra pure water and are sterile filtered. Each kit contains a dilution table to create any pH (between 5.0 & 8.2) and any concentration (between 0.2 & 4.0 M) in 0.2 increments. Crystallization accessories are sold separately.

Quik Optimize 试剂套装旨在提供灵活的基于磷酸盐试剂的溶解度和结晶筛选方法，用于生物大分子的结晶。快速优化可以方便、简单地再现原始 Quik 屏幕条件。该试剂盒特别适用于改进和优化使用 Quik Screen 确定的初步成功结晶条件。

Quik Optimize 由两种高纯度、无菌过滤储备溶液组成：4.0 M 磷酸二氢钠一水合物（NaH2PO4 Mr 137.99 CAS 编号 [10049-21-5]）和 4.0 M 磷酸氢二钾（K2HPO4 Mr 174.18 CAS 编号 [7758-11] -4]) 使用超纯水配制。最终试剂的 pH 值由磷酸钠和磷酸钾试剂的比例决定。提供的稀释表使浓度和 pH 值的测定快速而简单。使用 Quik Optimize 可以方便地配制 0.2 和 4.0 M 之间的 0.2 M 增量的试剂浓度和 5.0 和 8.2 之间的 0.2 pH 增量的 pH 值。

Quik Optimize 配方已成功用于生物大分子 1-7 结晶的晶体学和生物分离应用。 Quik Optimize 中的磷酸盐试剂系统是一种用于筛选和优化生物大分子结晶条件的稳定、灵活、易于复制、经济高效且简单的方法。 Quik Optimize 由 Macrocrystal Oy 开发，由 Hampton Research 独家制造和分销。

每个 Quik Optimize 试剂盒包含 4.0 M 磷酸二氢钠一水合物和 4.0 M 磷酸氢二钾试剂，各 100 ml。这些即用型试剂使用高纯度盐和超纯水配制而成，并经过无菌过滤。每个试剂盒都包含一个稀释表，以 0.2 为增量创建任何 pH 值（5.0 和 8.2 之间）和任何浓度（0.2 和 4.0 M 之间）。结晶配件单独出售。

描述

To screen pH as a crystallization variable using Tacsimate one can mix together different ratios of different pH Tacsimate solutions. Refer to the pdf “Mixing Tacsimate Stocks to Screen pH” on this page. Or, one can add a buffer to the crystallizaiton reagent containing Tacsimate. Recommended final buffer concentration in the reagent well is 0.05 to 0.1 M.

Tacsimate
A pH titrated mixture of organic acids. 1.8305 M Malonic acid, 0.25 M Ammonium citrate tribasic, 0.12 M Succinic acid, 0.3 M DL-Malic acid, 0.4 M Sodium acetate trihydrate, 0.5 M Sodium formate, 0.16 M Ammonium tartrate dibasic. pH adjusted using NaOH

Measured pH of 100% Tacsimate is 4.0 at 25°C
Measured pH of 100% Tacsimate is 5.0 at 25°C
Measured pH of 100% Tacsimate is 6.0 at 25°C
Measured pH of 100% Tacsimate is 7.0 at 25°C
Measured pH of 100% Tacsimate is 8.0 at 25°C
Measured pH of 100% Tacsimate is 9.0 at 25°C

为了使用 Tacsimate 将 pH 值筛选为结晶变量，可以将不同比例的不同 pH 值的 Tacsimate 溶液混合在一起。请参阅本页上的 pdf“混合 Tacsimate 库存以筛选 pH 值”。或者，可以将缓冲液添加到含有 Tacsimate 的结晶试剂中。试剂孔中推荐的最终缓冲液浓度为 0.05 至 0.1 M。

CrystalCap Magnetic & CrystalCap Copper Magnetic handling tool

描述

The CrystalWand Magnetic is designed to be used exclusively with the CrystalCap, CrystalCap ALS, and CrystalCap SPINE systems during transfer of the caps from the vial to the goniometer head and from the goniometer to the vial. The 6 1/2” (165 mm) long chrome plated steel wand features a plastic housing enclosing a spring tensioned plunger that when depressed, moves a non-magnetic steel platform away from the magnet housed in the end of the wand. This causes the steel CrystalCap to detach from the wand and be placed readily into the vial. When the platform is retracted, the wand securely holds the steel CrystalCap Magnetic.

CrystalWand Magnetic 专为 CrystalCap、CrystalCap ALS 和 CrystalCap SPINE 系统而设计，可在将瓶盖从样品瓶转移到测角仪头部以及从测角仪转移到样品瓶期间使用。 6 1/2 英寸（165 毫米）长的镀铬钢棒具有一个塑料外壳，其中包含一个弹簧拉紧的柱塞，当按下该柱塞时，将一个非磁性钢平台从棒末端的磁铁移开。这会导致钢 CrystalCap 从棒上分离并轻松放入小瓶中。当平台缩回时，魔杖会牢固地固定钢 CrystalCap Magnetic。
