Product Description:

Poly-L-lysine trifluoroacetate is a positively charged synthetic polyamino acid having one TFA per lysine unit. It is a crystalline solid soluble in water and polar organic solvents such as alcohols, DMF, DMSO or DMA. Applications for poly-L-lysine trifluoroacetate include the conjugation to active molecules for improved activities and the layer-by-layer deposition techniques.

Our poly-L-lysine trifluoroacetate has been purified by dialysis, sterile-filtered on 0.2um, lyophilized, and stored under Ar.
