Product Description:

Poly-L-aspartic acid sodium salt is a negatively charged synthetic polyamino acid having one Na per aspartic acid unit. It is a crystalline solid soluble in water. Applications for poly-L-aspartic acid sodium salt include the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques for surface coating, the mineralization of bone, and the water treatment.

Our poly-L-aspartic acid sodium salt has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
