Sodium malonate  丙二酸钠

APPLICATIONS  应用

  • Crystallization grade Sodium malonate for formulating screens or for optimization用于筛选或优化的结晶级丙二酸钠

FEATURES  特征

  • Sterile filtered solution
  • Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)
  • 无菌过滤液
  • 在1+超纯水中配制：在25°C下电阻率为18.2兆，总有机碳<5 ppb，无细菌(<1细菌(CFU/ml))，无热原(<0.03内毒素(EU/ml))，无RNase(<0.01 ng/mL)和无DNase(<4 pg/L)

DESCRIPTION

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.

描述

Hampton研究提供的丙二酸钠是苹果酸(化学文摘社编号141-82-2)，使用氢氧化钠滴定至pH4.0-8.0，载于出版物“大分子结晶盐的比较”，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都更成功，导致23种大分子中的19种结晶，几乎是第二种最成功的盐的两倍，即乙酸钠、酒石酸钠、甲酸钠和硫酸铵之间的结晶。当考虑到单个大分子的整体独特成功率时，丙二酸钠在晶体生产中的高成功率更令人印象深刻。

有报道称，用丙二酸钠代替硫酸铵可提高晶体的重现性，提高其抗物理化学冲击的能力。丙二酸钠也是一种良好的冷冻保护剂(邢和旭，2003年)。

一种方法是将四种不同的丙二酸钠组合起来，形成一个pH值相对于丙二酸钠浓度的网格，用于筛选或优化。请参阅丙二酸钠的pH/稀释表。

根据氢氧化钠滴定丙二酸的结构，不存在手性碳，不具有对映体结构，如D或L。

Crystals after Izit

Description
A crystal! Is it protein or is it salt? Have you ever asked yourself this question? Sure you could mount the crystal in question and take a quick look at the diffraction pattern but perhaps you’re too lazy or you don’t have an x-ray facility. Well, there’s always the crush test. One simply takes a MicroTool™ or Crystal Probe™ and crushes the suspect crystal. A click or solid crunch is indicative of salt while a powder or silent destruction might indicate one just destroyed a perfectly good protein crystal. Izit is here to help. Simply place 1 µl of Izit in the sample drop and wait for an hour or so. Izit is a small molecule dye which will fill the solvent channels in protein crystals, coloring the crystals blue. With the appropriate dilution, Izit will in fact leave a clear drop with blue crystals, as illustrated in the picture above. Salt crystals do not possess these large solvent channels. Therefore, Izit cannot enter the crystal, leaving one with a clear crystal and a blue drop. Izit is especially nice for small microcrystals or questionable precipitate. The 0.5 ml vial of Izit is sufficient for more than thousands of crystallization drops.

Each Izit vial contains 0.5 ml of Izit dye. All solutions are formulated using ultra-pure water and are sterile filtered. Crystallization accessories are sold separately.

伊兹特之后的水晶

描述
一个水晶！是蛋白质还是盐？你有没有问过自己这个问题？当然，您可以安装有问题的晶体并快速查看衍射图，但也许您太懒了，或者您没有 X 射线设备。好吧，总是有粉碎测试。只需使用 MicroTool™ 或 Crystal Probe™ 即可粉碎可疑晶体。咔嗒声或固体嘎吱声表示盐分，而粉末或无声破坏可能表示刚刚破坏了完美的蛋白质晶体。 Izit 是来帮忙的。只需将 1 µl Izit 放入样品滴中并等待一个小时左右。 Izit 是一种小分子染料，可填充蛋白质晶体中的溶剂通道，使晶体呈蓝色。通过适当的稀释，Izit 实际上会留下带有蓝色晶体的清晰液滴，如上图所示。盐晶体不具有这些大的溶剂通道。因此，伊兹特无法进入水晶，留下一个透明的水晶和蓝色的水滴。 Izit 特别适用于小微晶或可疑沉淀物。 0.5 毫升的 Izit 小瓶足以容纳超过数千滴结晶滴。

每个 Izit 小瓶含有 0.5 毫升 Izit 染料。所有溶液均使用超纯水配制并经过无菌过滤。结晶配件单独出售。

Primary or secondary, polymer, salt and pH matrix crystallization screen for biological macromolecules

Features

Developed at Hampton Research
PEG/Ion is a sparse matrix profile of anions and cations in the presence of monodisperse Polyethylene glycol 3,350 over pH 4.5 – 9.2
PEG/Ion 2 screens a complete profile of titrated organic acids at varying pH levels (3.7 – 8.8) in the presence of monodisperse PEG 3,350
PEG/Ion HT combines PEG/Ion and PEG/Ion 2 in a single 96 Deep Well block
 Description

PEG/Ion, developed by Hampton Research, is a crystallization screen designed to evaluate monodisperse, high purity Polyethylene glycol 3,350 and 48 unique salts representing a very complete range of anions and cations frequently used in the crystallization of biological macromolecules. The primary screening variables are PEG, ion type, ionic strength, and pH. More than 60% of the published crystallizations utilized PEG as a primary crystallization reagent and in approximately 50% of those reports, the PEG was combined with an ion as a secondary crystallization reagent. PEG/Ion reagents are formulated without a buffer and are not pH titrated.

PEG/Ion 2 is an extension to the fundamental crystallization strategy in PEG/Ion. PEG/Ion 2 reagents cover the monodisperse, high purity Polyethylene glycol 3,350 and an array of neutralized and pH adjusted organic acids, multivalent ions, a novel Citrate BIS-TRIS propane buffer system and pH (4 – 8.8). The formulation of PEG/Ion 2 was developed at Hampton Research. Each of the 48 reagents in PEG/Ion 2 contains PEG 3,350 as the polymer (precipitant). The concentration of PEG is varied from 12% w/v to 20% w/v depending upon the type and concentration of buffer/salt paired with the polymer. Thirteen of the forty-eight PEG/Ion 2 reagents contain a separate buffer component. The remaining PEG/Ion 2 reagents are buffered by the titrated organic acid salt. Six of these thirteen conditions feature a novel Citric acid BIS-TRIS propane (CBTP) buffer. The CBTP buffer uses Citric acid and BIS-TRIS propane as the acid base pair to create a two component buffer system effective across pH 2.5 to 9.5. The ratio of Citric acid to BIS-TRIS propane determines the solution pH. Thirty-five of the forty-eight PEG/Ion 2 reagents contain a neutralized or pH adjusted organic acid in the presence of the polymer. Neutralized organic acids are highly effective crystallization salts.1 Four PEG/Ion 2 reagents feature polyvalent cations. Two of these reagents contain cation mixes, saving sample by screening six different cations with only two reagents. Tryptone, a casein digest combinatorial library of peptides, is included in PEG/Ion 2. PEG/Ion 2 reagents 1-30, 42, 45-47 are formulated without a buffer and are not pH titrated.

PEG/Ion contains 48 unique reagents, 10 ml each.

PEG/Ion 2 contains 48 unique reagents, 10 ml each.
