Our scientists, having more than 15 years experience in the synthesis of polyamino acids, have developed a polymerization process that enables us to have complete control over the molecular weight of our polyamino acids without the use of metal catalysts. Furthermore, not only does the process enable us to achieve exact chain lengths but also highly monodisperse products (polydispersity index: 1.01-1.2) and batch-to-batch consistency.
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.
