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.

1.0 M 磷酸氢二钠二水合物在 4 摄氏度和更高温度下完全溶于水。 低于 4 摄氏度 1.0 M 磷酸氢二钠二水合物将从溶液中结晶出来。 如果发生这种情况,请将试剂加热到 37 度,直到观察到完全溶解(4 到 8 小时),然后将试剂储存在 4 到 25 摄氏度之间。
