 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.
