Glycerol  蛋白结晶蒸汽扩散结晶实验中添加甘油

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. Reference: Vera,L., Czarny, B., Georgiadis, D., Dive, V., Stura, E.A. (2011) Practical Use of Glycerol in Protein Crystallization. Cryst. Growth & Des. 11 :2755–2762

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

What additive to use  蛋白结晶用用什么添加剂

When trying to decide which additive might be useful during crystallization, try the following. If one has crystals and wants to try using additives to improve the crystal size or quality go back to the initial crystallization screening plates. Review the plates, looking for conditions where no precipitate nor crystals were/are observed. Now, review the results, looking for a common reagent ingredient present where no precipitant or crystals are found. For example, one might find that all drops with isopropanol remained clear. One could then try adding isopropanol to the current crystallization condition to see if the isopropanol could improve the crystal size and/or quality. If one observes a difference in the crystal in the presence of isopropanol, then one might consider evaluating other additives in the class of alcohols such as ethanol, methanol, tert-butanol and others. If one has no crystals, but plenty of precipitate, phase separation and clear drops, follow the above analysis and try adding the common reagent ingredient found in clear drop to those drops which contained precipitate or phase separation. It is possible this agent could improve or at least manipulate sample solubility. The above tip was submitted from Jarmila Jancarik from the laboratory of Sung Ho Kim at the University of California Berkeley. Thank you Jaru! When using this approach it might be reasonable to discern between concentration independent and dependent precipitation when trying to decide which agent to pursue as an additive. Try evaluating the concentration independent agents first and then look at the other agents if sample quantity permits. For example, if one observe precipitate in 15 to 40% PEG but not in 5 to 10% PEG, it might simply be a concentration. However, if one observes no precipitate in 45 to 60% v/v MPD one could guess that MPD is a reasonable agent to evaluate as an additive.

当试图决定在结晶过程中哪种添加剂可能有用时，请尝试以下方法。如果有晶体并想尝试使用添加剂来改善晶体尺寸或质量，请返回最初的结晶筛选板。检查板，寻找没有观察到沉淀或晶体的条件。现在，查看结果，寻找没有发现沉淀剂或晶体的常见试剂成分。例如，人们可能会发现所有含有异丙醇的液滴都保持透明。然后可以尝试将异丙醇添加到当前的结晶条件中，以查看异丙醇是否可以改善晶体尺寸和/或质量。如果在异丙醇存在下观察到晶体的差异，那么可以考虑评估醇类中的其他添加剂，例如乙醇、甲醇、叔丁醇等。如果没有晶体，但有大量的沉淀、相分离和透明液滴，请按照上述分析，尝试将透明液滴中常见的试剂成分添加到含有沉淀或相分离的液滴中。该试剂有可能改善或至少控制样品溶解度。上述提示由加州大学伯克利分校 Sung Ho Kim 实验室的 Jarmila Jancarik 提交。谢谢雅鲁！当使用这种方法时，在尝试决定使用哪种试剂作为添加剂时，区分与浓度无关的沉淀和依赖沉淀可能是合理的。尝试先评估与浓度无关的试剂，然后在样本数量允许的情况下查看其他试剂。例如，如果观察到 15% 到 40% PEG 中的沉淀，但 5% 到 10% PEG 中没有，则它可能只是一种浓度。然而，如果在 45 至 60% v/v MPD 中没有观察到沉淀，则可以猜测 MPD 是一种可以作为添加剂进行评估的合理试剂。

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。

描述

硅化玻璃覆盖幻灯片允许一个液滴悬浮在一个位置，为周围的储油层溶液的蒸汽扩散提供了近乎佳的条件。

这些硅化玻璃覆盖幻灯片提供了一个一致的，高质量的完成结晶实验。疏水性表面会产生一滴“很好”的水滴，在玻璃上不会变平。硅化表面防止晶体粘附并沉淀到玻璃表面。使用陶氏康宁真空润滑脂(HR3-510)或陶氏康宁7释放化合物(HR3-508)密封滑动板。可在12，18或22毫米直径圆和22毫米直径方格。有0.22毫米或0.96毫米玻璃厚度。0.96毫米厚的幻灯片在晶化处理过程中几乎是不可破碎的。

APPLICATIONS

  • Siliconized glass cover slides for hanging & sitting drop crystallization
  • Hanging drop crystallization
  • Sitting drop crystallization
  • Sandwich drop crystallization

FEATURES

  • High purity of glass
  • Siliconized, hydrophobic glass surface
  • 0.22 mm & 0.96 mm glass thickness
  • 12 mm glass diameter
  • Circle
  • 0.22 mm glass thickness is UV Compatible (>85% transmission)

DESCRIPTION

Siliconized glass cover slides allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution.

These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use Dow Corning Vacuum Grease (HR3-510) or Dow Corning 7 Release Compound (HR3-508) to seal cover slide to plate. Available in 12, 18 or 22 mm diameter circles and 22 mm diameter squares. Available in 0.22 mm or 0.96 mm glass thickness. The 0.96 mm thick slides are virtually unbreakable during crystallization handling.

Hampton HR3-508 Dow Corning 7 Release Compound Grease

发表于由

Hampton HR3-508 Dow Corning 7 Release Compound Grease

APPLICATIONS

  • Grease sealant for hanging, sitting, and sandwich drop vapor diffusion set ups.

应用
用于悬挂式、坐式和夹层式液滴蒸汽扩散装置的润滑脂密封剂。

DESCRIPTION

The Dow Corning® 7 Release Compound Grease sealant is similar to vacuum grease but is less viscous. Being less viscous, it is easier to push through a syringe when applying the sealant manually. Squeeze the grease into a 10 cc syringe fitted with a 200 µl pipet tip trimmed to desired diameter and you are ready to grease.

描述
道康宁® 7 离型复合润滑脂密封剂类似于真空润滑脂，但粘性较低。 由于粘性较小，手动涂抹密封剂时更容易推动注射器。 将润滑脂挤入装有 200 µl 移液管尖端的 10 cc 注射器中，并修剪到所需的直径，您就可以润滑了。
