Hampton GRAS 3 • GRAS 4 Screens
Applications
a.GRAS reagent crystallization screen for proteins, including monoclonal antibodies, where Salt is the primary, and Polyethylene glycol the secondary reagent, sampling pH 4-9
b.Identify GRAS based reagents that promote crystallization of biotherapeutics for bioprocess, bioformulation, and continuous flow manufacturing applications
Features

 Description
GRAS Screen™ 3 and GRAS Screen™ 4 were developed by Hampton Research for the crystallization of proteins, including monoclonal antibodies. Each of the chemicals in GRAS Screen 3 and 4 have been used under one or more of the following categories. As (1) a Generally Recognized As Safe (GRAS) substance, (2) a pharmaceutical excipient, (3) a normal physiological constituent, (4) a metabolic byproduct, and/or (5) a Everything Added to Food in the United States (EAFUS) substance.

GRAS Screen 3 samples twenty four salts, encompassing pH 4-9 versus four low molecular weight Polyethylene glycols (300, 400, MME 550, & 600). GRAS Screen 3 is supplied in a 96 Deep Well block format and is compatible with robotic and multi-channel pipet liquid handling systems. GRAS Screen 3 is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.
GRAS Screen 4 samples twenty four salts, encompassing pH 4-9 versus four medium molecular weight Polyethylene glycols (1,000, MME 2,000, 3,350 & 4,000). GRAS Screen 4 is supplied in a 96 Deep Well block format and is compatible with robotic and multi-channel pipet liquid handling systems. GRAS Screen 4 is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.

HDP Hanging Drop Plate

Single Well with Tool

Hanging Drop Wells
Applications—Hanging drop crystallization
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.
