Features

  Made from optically superior polymer (UVP)

  Allen key novel crystal plug closure system

  Wells are micro-numbered

Description  描述:
The Swissci Hanging Drop Crystallization Plate is a breakthrough for protein crystallization in a 96-well format. For the first time individual wells can be identified and removed without any disturbance to the growing crystals inside the plate.Description

The plate has been developed by Swissci AG together with leading Crystallographers. It is the result of many years of experience in successful robotic high-throughput crystallization.

The Hanging Drop Crystallization Plate offers unique properties that make it ideal for both nanoliter crystallization screening and microliter optimization alike. Made from optically superior polymer (UVP) and with a new design of the wells, the plate allows easy crystal viewing and retrieval. The system is fully covered by design and patent protection.

The Advantages of the Hanging Drop Crystallization Plate

Easy Crystal Retrieval
Raised wide wells make the crystal mounting especially easy. Allen key system allows for smooth removal and subsequent microscopic investigation / X-ray with the novel crystal plug closure all included in the system.

Easy Viewing
The wells are wide conical and have a lens effect for perfect illumination. The micro-numbering ensures you will never loose the location under the microscope.

The optically superior polymer is UV transmissible and can be used to differentiate between salt and protein crystals.

Integral Sealing
Wide partition walls between each well provides a high surface area for very good sealing with the advanced quality sealing tape. The sealing tape is integrated into the kit so there is no need to purchase additional parts prior to starting a procedure.

Wide Range of Volumes
Typical volumes are 50 – 200 µl of reservoir and 10 nanoliter – 5 microliter drop size.

SBS Standard
The complete plate is designed to the 96-well SBS standard for all common holders.

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.

      上海金畔生物作为Hampton蛋白结晶产品的代理商,竭诚为您服务,欢迎新老客户咨询。

Description 描述
Glass Number 50 (borosilicate glass) capillaries that are extremely thin walled (approximately 10 micron wall thickness). The length of the capillary has a well defined diameter, with one end having a funnel shape and the other end closed. Glass capillaries have a wall thickness of 0.01 mm and an overall length of 80 mm +/- 5 mm. Glass capillaries are available in a wide range of outside diameters from 0.1 mm to 2.0 mm. They are designed to mount, hold, and store small molecule and biological macromolecular crystals for x-ray data collection. Capillaries can also be used for crystal density measurements and crystal growth experiments. The capillaries can be sealed tightly against moisture and gases using wax, epoxy, or other sealing materials.

In determining what glass or quartz capillary is right for you, please refer to the “Linear Absorption Coefficient µ cm-1” table. This table indicates the amount of radiation that is absorbed by the capillary during x-ray data collection.

For 0.1 mm to 2.0 mm capillaries the open end capillary tube base size is 3.0 +/- 0.15 mm OD x 0.13 +/- 0.10 mm Wall thickness.

The Diameter is measured 40 mm from the closed end. The tolerances are as follows

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.
