Poly-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-L-lysine hydrobromide include the promotion of cell adhesion to solid substrates for culture dishes or slides, the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques, and the complexation with nucleic acids for gene expression.
This particular poly-L-lysine hydrobromide has an azide function on the C-terminal.
Our polyamino acid has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
Store azido-poly-L-lysine hydrobromide under the condition of flushing with argon and protecting from light, and below -15°C.
