Hampton  MembFac • Crystal Screen Lite • MembFac HT

Features
  Membrane protein sparse matrix screens
  Sparse matrix formula efficiently samples salts, polymers, organics and pH
  pH range 4.6 – 8.5
  Formulated for use with detergents
   Tube or Deep Well block format
   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.
