 Description
Natrix, Natrix 2 and Natrix HT are based upon published reagent formulations for the crystallization of nucleic acids and protein-nucleic acid complexes. A variety of hammerhead ribozymes and other ribozymes, RNAs, DNAs, RNA-drug complexes, and RNA-protein complexes have been crystallized using the Natrix protocols.By using sparse matrix sampling technology, The Natrix kits allow one to quickly test wide ranges of pH, salts, and precipitants using a very small sample of nucleic acid.Natrix screens are unique in that rather than relying solely on the traditional nucleic acid precipitant MPD, Natrix screens also utilize Polyethylene glycols (PEGs) in a variety of molecular weights (200, 400, 4,000, 8,000) as well as 2-Propanol, Polyethylene glycol monomethyl ether (PEG MME), and 1,6-Hexanediol. Many of the polymeric and low molecular weight organic precipitants are combined with various monovalent salts as precipitating agents. This combination of salts and low molecular weight organics and polyalcohols, as well as the utilization of varying chain length PEGs, has proven to be a successful combination for producing nucleic acid and protein-nucleic acid complex crystals.Natrix contains 48 unique reagents, 10 ml each and is based on the sparse matrix formulation first described by William Scott in 1995.Natrix 2, an extension of Natrix, contains 48 unique reagents, 10 ml each. Natrix 2 is a biased sparse matrix screen based on extracting patterns from crystallization data as well as reagent formulations first described by Berger et al in 1996.

Natrix HT contains 1 ml of each reagent from Natrix and Natrix 2 in a single Deep Well block format.

Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

描述

Natrix,Natrix 2和Natrix HT是以已发表的核酸和蛋白质-核酸复合物结晶试剂配方为基础的。各种锤头状核酶和其他核酶、RNA、DNA、RNA-药物复合物和RNA-蛋白质复合物已通过Natrix程序结晶。

通过使用稀疏矩阵取样技术,Natrix试剂盒允许使用非常小的核酸样本快速测试范围广泛的pH、盐类和沉淀剂。

Natrix筛网的独特之处在于,它不仅依靠传统的核酸沉淀剂MPD,而且还在各种分子量(200、400、4000、8000)以及2-丙醇、聚乙二醇单甲醚(PEG MME)和1,6-己二醇中使用聚乙二醇乙二醇(PEGS)。许多高分子和低分子量有机沉淀剂与各种单价盐结合作为沉淀剂。这种盐与低分子量有机物和聚醇的结合,以及利用不同的链长钉,已被证明是生产核酸和蛋白质-核酸复合物晶体的成功组合。

Natrix含有48种独特的试剂,每种10毫升,是基于1995年威廉·斯科特首次描述的稀疏矩阵公式。

Natrix 2是Natrix的扩展,包含48种独特试剂,每个10毫升。Natrix 2是一种基于从结晶数据和试剂配方中提取模式的有偏稀疏矩阵筛选器,由Berger等人于1996年首次描述。

Description
The Crystal Screen and Crystal Screen 2 reagent kits are designed to provide a highly effective and rapid screening method for the crystallization of macromolecules. The screens are simple and practical for finding initial crystallization conditions. The initial crystallization conditions for more than 1,000 proteins, peptides, oligonucleotides, and small molecules have been determined using Crystal Screen.

A highly effective approach to overcome the exhaustive search for suitable crystallization conditions is the use of a sparse matrix method of trial conditions that is biased and selected from known crystallization conditions for macromolecules. The formulation utilized in Crystal Screen and Crystal Screen 2 evaluates 96 unique mixtures of pH, salts, polymers and organics, and their ability to promote crystal growth.

Crystal Screen contains 50 unique reagents, 10 ml each and is based on the sparse matrix formulation first described by Jancarik and Kim in 1991.

Crystal Screen 2, an extension of Crystal Screen, contains 48 unique reagents, 10 ml each and is based on the formulation first described by Cudney et al in 1994.

Features

  Membrane protein sparse matrix screens

  Sparse matrix formula efficiently samples salts, polymers, organics and pH

  pH range 4.6 – 8.5

   Crystal Screen Lite features a lower ionic strength than the original Crystal Screen

Description
MembFac is a highly effective sparse matrix screen specifically designed as a preliminary screen for the crystallization of membrane proteins. MembFac is based upon the highly effective biased sparse matrix methodology. The MembFac screen matrix is optimized for the crystallization of membrane proteins.

MembFac contains 48 unique reagent formulations. With this set of 48 conditions, numerous chemicals and chemical combinations are utilized, allowing one to evaluate a large variety of potential crystallization conditions. MembFac covers a broad pH range between 4 and 9.

The Rationale
The basic rationale of MembFac is to perform a sparse matrix screen while changing the detergent dimension because detergents play an important factor in the crystallization of membrane proteins. A MembFac screen is to be completed for each detergent. Detergent screens are available separately.

The Method
The membrane protein of interest is first isolated in the detergent which gives the highest stability and activity. The protein concentration should be approximately 10 to 20 mg/ml and the detergent concentration should be only slightly above the CMC. The sample is then set against MembFac, using all 48 solutions plus the screening detergent(s) of choice. The screening detergent concentration should be approximately one to three times the CMC. Hence, for each detergent screened, one would utilize approximately 1 to 2 mg of sample.

The MembFac protocol was used to crystallize membrane proteins including SQR, fumerate: quinone oxireductase, LHII, and LHCII.

Crystal Screen Lite is a sparse matrix of trial crystallization reagent conditions based upon the Crystal Screen™.3 The primary screen variables are salt, pH, and precipitant (salts, polymers, volatile organics, and non-volatile organics).2Crystal Screen Lite differs from the original Crystal Screen kit in that the primary precipitant reagents are one-half the concentration of that used in the original Crystal Screen formulation. The secondary salts, ions, and buffers remain at the original Crystal Screen concentration. Reducing the primary concentration of the primary precipitant results in a screen which is “more gentle” on the sample and typically produces much less precipitate conditions than the original Crystal Screen.

MembFac contains 48 unique reagents, 10 ml each.

MembFac HT contains 1 ml each of all 48 reagents from MembFac and reagents 1-48 from Crystal Screen Lite in a single Deep Well block format.

Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Description

Solubility & Stability Screen is designed to assist in the identification of solution conditions which promote protein solubility and stability, and minimize protein precipitation. Solubility & Stability Screen is a solubility screen, a stability screen, and may also be used as an additive screen in the presence of a crystallization reagent.

The Hampton Research Solubility and Stability Screen can evaluate protein solubility, stability and crystallization in the presence of 94 different chemical additives sampling 17 different classes of reagents plus two controls.

Protein solubility and stability are universally required in a wide range of applications, including general biochemical studies, the preparation of proteins in pharmaceuticals, structural biology and crystallization.1-11The preparation of a concentrated, soluble and stable protein sample can often be a difficult task as proteins often aggregate, precipitate or denature.

Thermofluor (also known as Differential Scanning Fluorimetry, DSF and Protein Thermal Shift) provides a rapid, convenient and effective means of identifying subsaturating solution conditions that may also correlate with protein heterogeneity and poor crystallization outcomes.12

Protein solubility and stability is affected by many different chemical factors including pH, buffer type, chemical additives and excipients. pH and buffer type are dominant protein solubility and stability variables and can be evaluated and optimized using the Hampton Research Slice pH kit HR2-070. Slice pH evaluates protein solubility, stability and crystallization versus 20 different buffers over the pH range 3.5-9.6. Chemical additives influencing protein solubility and stability can be evaluated using the Solubility & Stability Screen.

It is widely accepted that protein solubility and stability can be increased by the use of chemical additives.5,15Seventeen classes of reagents are sampled by the Solubility & Stability Screen and each of these classes has been reported as important in improving sample solubility and stability.2-11

The Solubility & Stability Screen is a set of 94 high purity reagents formulated in high purity water (NCCLS/ASTM Type 1+) at 25°C and are 0.22 micron sterile filtered. The 94 solubility and stability reagents are formulated at 2 to 10 times their recommended working concentration. The remaining two reagents are water and a negative (TCA) control. A water control demonstrates the effect of diluting sample as well as sample buffer concentration. TCA, the negative control, demonstrates total sample precipitation, loss of sample solubility and loss of sample stability. The effects of the Solubility & Stability reagents can be compared with this negative control to assist in the identification of reagents promoting sample solubility and stability. 500 microliters of each reagent is supplied in a sterile 96 well polypropylene Deep Well block. The Solubility & Stability Screen reagents are compatible with the sitting or hanging drop vapor diffusion, microbatch, free interface diffusion, sandwich drop vapor diffusion, and dialysis crystallization methods utilizing water soluble reagents.

Plain, non-siliconized, hydrophilic glass cover slides. Useful for hanging drop, sitting drop, and sandwich drop vapor diffusion crystallization methods. The hydrophilic surface creates a drop which is more flat than a drop on a siliconized surface. This offers enhanced imaging for very small drops. Use Dow Corning® Vacuum Grease (HR3-510), Dow Corning® 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate.HR3-209T 12 mm Plain circle cover slides for Tecan robot 5 oz case (~2,400 slides)
