Application

High molecular weight poly-γ-glutamic acid (γPGA) was found to increase levels of NK cell-mediated cytotoxicity and INF-γ secretion in C57BL/6 mice. Biodegradable γ-PGA nanoparticles have been evaluated for use as antigen delivery carriers and delivery of influenza virus hemagglutin (HA) vaccine. Additional life science applications for γ-PGA include uses in biodegradable fibers and nanofiber sheets, hydrogels, and cryoprotectants.

Other Notes

High molecular weight poly-γ-glutamic acid is a polymer of glutamic acid connected by amide linkages between α-amino and γ-carboxylic acid groups. γ-PGA is produced by fermentation in Bacillus species. The subunits are predominantly L-isomer.

Adding poly(gamma-glutamic acid) nano-particles (gamma-PGA-NPs), a safe, natural material, to subcutaneous immunization with influenza virus hemagglutinin (HA) vaccine increases the protective immune responses against influenza virus in mice. Here, we examined whether intranasal administration of the HA vaccine with gamma-PGA-NPs

We analyzed the in vivo tumor regression activity of high molecular mass poly-gamma-glutamate (gamma-PGA) from Bacillus subtilis sups. chungkookjang. C57BL/6 mice were orally administered 10-, 100-, or 2000-kDa gamma-PGA or beta-glucan (positive control), and antitumor immunity was examined. Our results
