 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.

Description
Index is designed as a 96 reagent crystallization screen that combines the strategies of the grid, sparse matrix, and incomplete factorial screening with traditional, contemporary, and new crystallization reagent systems into a highly effective and efficient format.
Index, as the name implies, efficiently samples a series of specially formulated reagent zones to identify which reagent class or classes and pH are effective in producing crystals or limiting sample solubility. Results from Index can be used to design optimization experiments and to identify follow on screens by reagent class. For example, positive results with salt based reagents in Index may be followed up with further screening using SaltRx or Grid Screen Salt HT. Success with polymer based reagents in Index may be followed up with further screening using PEGRx or PEG/Ion.
Index utilizes a broad, yet refined portfolio of crystallization reagent systems. These include the following: (1) traditional salts such as Ammonium sulfate and Sodium chloride versus pH; (2) neutralized organic acids such as Sodium malonate and Tacsimate; (3) High salt concentration mixed with low polymer concentration as well as high polymer concentration mixed with low salt concentration and; (4) Low ionic strength using polymers such as PEG, MPD, Pentaerythritols versus pH. These reagent systems are formulated across a sparse matrix and incomplete factorial of concentration ranges, sampling a pH range of 3 to 9.
Index contains 96 unique reagents, 10 ml each.
Index HT contains 96 unique reagents 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 蛋白结晶试剂–Crystal Screen
Crystal Screen • Crystal Screen 2 • Crystal Screen HT

Applications
 Primary screen for proteins, soluble peptides, nucleic acids, & water soluble small molecules
 Sparse matrix additive screen
Features
 The original sparse matrix screen
 Sparse matrix formula efficiently samples salts, polymers, organics, & pH
 Proven effective with more than 1,000 biological macromolecules
 Tube or Deep Well block format

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.
Crystal Screen HT contains 1 ml each of reagents 1-48 from Crystal Screen and all 48 reagents from Crystal Screen 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 CrystalEX Second Generation (Corning)

Hampton CrystalEX Second Generation (Corning)
Crystal<i>EX</i> Second Generation (Corning)
CrystalEx Plates
Applications
   Sitting drop crystallization
Features

96 well sitting drop plate
Round and conical flat bottom drop well shapes
1, 2 or 4 microliter drop wells
1, 3 or 5 drop wells per reservoir
Hydrophilicity treated or untreated
PZero or COC plate material–UV imaging compatible

Description
The second generation of Corning® 96 Well, sitting drop format plates are built to SBS specifications, making them well suited for high throughput crystallization and are fully compatible with robotic equipment. The plates are available in several different configurations with varying drop well shapes, plate materials, and number of drop wells per reagent well. The basic plate design is one reagent well flanked by one or three drop wells, with SBS standard spacing between the centers of adjacent well clusters. One may choose a plate with small (1 µl), medium (2 µl), or large (4 µl) drop well volumes. The choice of round or conical flat well shapes are available. The PZero polymer provides for zero background polarization and is non-birefringent. PZero plates are not treated. The COC polymer offers high chemical resistance. Both types of plastic feature improved transparency. The reservoir numbers are embossed on each individual well for easy identification. Drop well locations conform to SBS standards for robotic handling. The low-volume reagent well saves on reagent costs. The plates can be sealed using Crystal Clear Sealing Film (HR3-609), 3 inch wide Crystal Clear Sealing Tape (HR4-506) or ClearSeal Film™ (HR4-521).
