General description
Toyopearl HW-40 resin is a hydroxylated methacrylic polymer for size exclusion chromatography. It is typically used for high throughput desalting and buffer exchange. It also can remove surfactants such as Triton X100 from protein solutions. It is often used for smaller biomolecules with exclusion limits up to 10,000 Da.
Application
TOYOPEARL® media fractionate mixtures of proteins and other large molecular weight compounds over a wide size range. Applications include separating RNA from protein, resolving oligosaccharides by degree of polymerization, and isolating agglutinin while maintaining a high hemagglutination titer.
Specifications
Clean in place with 0.5 M NaOH or 0.1 M HCl.
Physical form
Shipped in 20% (v/v) ethanol.

A method is developed for the preparation of D-rhamnose from an O-polysaccharide (OPS) isolated by mild acid hydrolysis of Azospirillum brasilense SR75 cell mass. After the OPS hydrolysis, D-rhamnose was recovered by gel-permeation chromatography on Toyopearl TSK HW-40 and was

We have cloned ansB (YPTB1411) gene from Yersinia pseudotuberculosis Q66CJ2 and constructed stable inducible expression system that overproduce L-asparaginase from Y. pseudotuberculosis (YpA) in Escherichiacoli BL21 (DE3) cells. For purification of YpA we used Q-Sepharose and DEAE-Toyopearl column chromatography. We
