多聚赖氨酸 PEG Conjugate，MW 5000 Da

Nanocs PLL-g-PEG, MW 5000 is a Poly-L-lysine PEG conjμgate made from by the covalent attachment of PEG 5000 to the L-polysine molecule via its amino grops. Conjμgate is provided in lyophilized powder form. There are typically 2-5 PEG5000 molecules on each poly-l-lysine. Average molecular weight of poly-L-ysine is 25 kD. PLL-g-PEG is a water soluble and positively charged PEG conjμgate that can be used for gene transfection as well as surface treatment.
