Poly-D-glutamic acid sodium salt is a negatively charged synthetic polyamino acid having one Na per glutamic acid unit. It is a crystalline solid soluble in water. Applications for poly-D-glutamic acid sodium salt include the conjugation to active molecules for improved activities and the layer-by-layer deposition techniques for surface coating.
Our poly-D-glutamic acid sodium salt has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
Store poly-D-glutamic acid sodium salt under the condition of flushing with argon and protecting from light, and below -15°C.
