Hampton Natrix • Natrix 2 • Natrix HT

Hampton Natrix • Natrix 2 • Natrix HT

Applications
  Primary biased sparse matrix crystallization screen for nucleic acids & protein/nucleic acid complexes  主要用于核酸和蛋白质/核酸复合物的删选
Features

Nucleic acid sparse matrix screen
Sparse matrix formulation efficiently samples salts, polyols, polymers, organics, additives & pH
pH range 5.6 – 8.5
Tube or Deep Well block format
 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.

Hampton AlumaSeal™ II Sealing Film and Applicator

Hampton AlumaSeal™ II Sealing Film and Applicator

Applications
Sealing film used to reseal HT format screen kits in polypropylene blocks and plates
Features
Excellent seal
Film conforms to raised chimney wells
Easily pierceable with single or multichannel pipettors and robotic probes
Heat & cold resistant, recommended for temperatures from -80 °C to +120 °C
Certified DNase-, RNase-, and nucleic-acid-free
Less evaporation than clear films
Excellent barrier properties, virtually no reagent evaporation or drying
 Description
A 38 µm soft non-permeable aluminum foil sealing film with strong medical-grade adhesive, AlumaSeal II sealing films eliminate the need for heat-sealing devices or mats during the resealing of reagents in polypropylene deep well blocks. Each sealing film measures 82.6 x 142.9 mm and offers sufficient sealing area for 96 deep well blocks. Length between the perforations with end tabs removed is 125.4 mm. Compared to other aluminum foils, AlumaSeal II has less tendency to roll back on itself when removing the backing paper and it conforms well to the plate during application.AlumaSeal II is a soft, pierceable adhesive film designed for the convenient and rapid sealing of polypropylene deep well blocks. A multiple split backing with two end tabs allows for easy, accurate positioning and secure sealing. The use of an adhesive sealing film minimizes evaporation and helps to prevent well-to-well cross contamination in reagent blocks. AlumaSeal II films are easily pierced by pipettte tips or robotic probes or piercing tools for direct reagent recovery without significant gumming by adhesive.

Use Solubility & Stability Screen along side Slice pH and Solubility & Stability Screen 2 to optimize sample buffer
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.
