Product Description

Poly-D-Lysine Hydrobromide

Application Notes

It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. Both the D- and L- form of the poly-lysine can be used as a coating substrate since poly-lysine is a nonspecific attachment factor for cells; however, certain cells can digest poly-lysine. In this case, poly-D-lysine should be used as the attachment factor so that the cells are not disrupted by excessive uptake of L-lysine.Other uses for poly-lysine have been reported as well:• Conjugation to methotrexate for increased drug transport.• Microencapsulation of islets.• Use in simple reproducible procedure for chromosomal preparations from a variety of tissues.• Immobilation of living cells in biocompatible semipermeable microcapsules.• In the preparation of polycationic beads.• Conjugation to albumin and horseradish peroxidase to enhance cellular uptake.
