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)

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。

DESCRIPTION  描述

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® is a trademark of Santovac® Fluids.

Description 
Similar to the Mounted CryoLoop™ in design and function, the Adjustable Mounted CryoLoop allows one to manipulate and orient the CryoLoop to multiple, unique positions previously unattainable with typical cryo setups. The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.

Using forceps or a probe one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.

Description
The CrystalWand Magnetic is designed to be used exclusively with the CrystalCap Magnetic, CrystalCap Copper Magnetic, and CrystalCap HT 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 or the CryoTong™. When the platform is retracted, the wand securely holds the steel CrystalCap Magnetic. The CrystalWand Magnetic 45° (McMiken Tool) offers the same functionality but is bent at a 45° angle at approximately 2.5 cm from the magnet end.

CryoTong™ – Long
Applications

Crystal transfer under cryo temperature
Features

Artery clamp style closure30 seconds of cryo temperature180 mm length
Description
The CryoTong is a tool used to manually transfer a crystal mounted on a CrystalCap™ from liquid nitrogen to a magnetic base in a goniometer head positioned in a cryogenic stream, and then back to liquid nitrogen. The one-piece, compact CryoTong is available in two lengths. The long CryoTong is approximately 180 mm in overall length. The artery clamp style maintains the CryoTong in the closed position until the clamp is squeezed, which opens the opposing heads. The heads are non-magnetic stainless steel. The handle is magnetic stainless steel. The inside of the head is machined to closely surround the CrystalCap with loop and crystal in place. A small retaining lip is machined into the lower portion of the head to prevent the CrystalCap from slipping out of the CryoTong when the tool is in the closed position. The CryoTong can maintain the temperature of the crystal at -160°C for up to 30 seconds during room temperature crystal transfers. Choose the proper CryoTong size based upon the pin length required by the configuration of the x-ray data collection hardware used. The 18 mm CryoTong (HR5-112) is to be used with the CrystalCap HT and any other CrystalCap configured for 18 mm.HR5-114 Long CryoTong 18 mm, 180° features the head in alignment with the handle of the CryoTong.

DESCRIPTION  描述

Additive Screen is a library of reagents that can affect the solubility and crystallization of biological macromolecules, including both soluble and membrane proteins.

These reagents can perturb and manipulate sample-sample and sample-solvent interactions, as well as perturb water structure which can alter and improve both the solubility and crystallization of a sample. Additives can stabilize or engender conformity by specific interaction with the macromolecules. There are numerous reports of the use of additives to improve the quality and size of macromolecular crystals.1-5
