Poly-D,L-lysine hydrobromide is a positively charged synthetic polyamino acid having one HBr per lysine unit. It is a crystalline solid soluble in water. Applications for poly-D,L-lysine hydrobromide include the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques, and the complexation with nucleic acids for gene expression.
Our poly-D,L-lysine hydrobromide has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
Store poly-D,L-lysine hydrobromide under the condition of flushing with argon and protecting from light, and below -15°C.
