Hampton Santovac Cryo Oil替代HR2-643 Parabar10312

APPLICATIONS

  • Oil based cryoprotectant

应用
油基冷冻保护剂

FEATURES

  • Low viscosity
  • Low surface tension
  • Cryoprotectant for soluble and membrane protein crystals
  • Not miscible with most solvents
  • Non toxic, non penetrating cryoprotectant

特征
低粘度
低表面张力
可溶性蛋白和膜蛋白晶体的冷冻保护剂
与大多数溶剂不混溶
无毒、非渗透性冷冻保护剂

DESCRIPTION

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.

Santovac (Santovac 5) 是一种具有极低蒸气压和低反应性的五环聚苯醚 (PPE)。该油具有很强的抗氧化性。纯聚苯醚中唯一的元素是氧、氢和碳。

该流体在正常工作温度下化学性质稳定、无腐蚀性、安全且无毒。

Santovac 与水、石蜡油、硅油、烷烃或 Parabar 10312 (Paratone) 不混溶。 Santovac 可与丙酮混溶。保质期5年。

Cryosalts   使用盐作为结晶试剂

Using salt as a crystallization reagent?

Many salts are cryosalts, including malonate, formate, citrate, tartrate, acetate, Tacsimate and other organic acids, ammonium sulfate (>3.5 M), lithium sulfate, lithium chloride and other alkylammonium salts. For cryo try increasing your salt concentration by 20%. (Cryosalts: suppression of ice formation in macromolecular crystallography, K. A. Rubinson et al, Acta Cryst. (2000). D56, 996-1001 doi:10.1107/S0907444900007587.

冰晶盐
使用盐作为结晶试剂？

很多盐是冰晶盐，包括丙二酸盐、甲酸盐、柠檬酸盐、酒石酸盐、乙酸盐、Tacsimate和其他有机酸、硫酸铵（>3.5 M）、硫酸锂、氯化锂和其他烷基铵盐。 对于冷冻，尝试将盐浓度提高 20%。 （冷冻盐：大分子晶体学中冰形成的抑制，K. A. Rubinson 等人，Acta Cryst. (2000). D56, 996-1001 doi:10.1107/S0907444900007587。

Benzylkonium chloride-膜蛋白和可溶性蛋白用阳离子表面活性剂

Try benzylkonium chloride (Fluka 12060). This cationic surface active agent has been reported to be useful as a crystallization additive with membrane proteins and may be useful for soluble proteins. We’ve been using it in the drop between 1 and 3% w/v in water. Try a 10% w/v stock solution in water and dilute into the drop to 1-3%.

苄基氯铵
试试苄基氯铵 (Fluka 12060)。 据报道，这种阳离子表面活性剂可用作膜蛋白的结晶添加剂，并可用于可溶性蛋白。 我们一直在水中使用 1% 到 3% w/v 的浓度。 尝试在水中使用 10% w/v 的储备溶液，然后将其稀释至 1-3%。

Glycerol  蛋白结晶蒸汽扩散结晶实验中添加甘油

Looking for yet another additive to try during optimization? Try glycerol. Typical concentrations in the drop can range from 3 to 15%. Glycerol may limit non-specific aggregation and could be useful if you plan to use cryo techniques during data collection.

When adding glycerol to the vapor diffusion crystallization experiment be sure to have a higher glycerol concentration in the reservoir than the drop otherwise you may find that your drops will get biggger and not smaller.

甘油
正在寻找另一种在优化过程中尝试的添加剂？ 试试甘油。 液滴中的典型浓度范围为 3% 至 15%。 甘油可能会限制非特异性聚合，如果您计划在数据收集期间使用冷冻技术，它可能会很有用。

在蒸汽扩散结晶实验中添加甘油时，请确保容器中的甘油浓度高于液滴，否则您可能会发现液滴会变得更大而不是更小。 参考： Vera,L.、Czarny, B.、Georgiadis, D.、Dive, V.、Stura, E.A. (2011) 甘油在蛋白质结晶中的实际应用。 水晶。 成长与发展。 11:2755–2762

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。
