货品编号： Sigma.P4707-50ML 品牌：Sigma 品名：Poly-L-LYSINE SOLUTION 规格：50ml 产品描述：

Components Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide

allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta

structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O

containing moieties.

Application

Poly-L-lysine polymers can be used in promoting cell adhesion to solid substrates, conjugation to methotrexate for increased

drug transport, microencapsulation of islets, cell microencapsulation technology, microarray glass slide coating, and

chromosomal preparations. Lower molecular weight poly-L-lysine (30,000-70,000) is less viscuous in solution, but higher

molecular weight versions provide more attachment sites per molecule.

•Poly-L-lysine coated glass coverslips have been used for mounting samples for scanning electron microscopy.[1] •Poly-L-lysine coated wells were used for trapping of PC-12 cells on electrodes.[2] •Poly-L-lysine-coated borosilicate glass slides were used for the seeding of viral vector-transduced cells.[3]
