Poly-L-lysine

Poly-L-Lysine is a synthetic amino acid chain that is positively charged and widely used as a coating substrate for culture dishes, slides, etc, to enhance cell attachment and adhesion to plasticware and glass surfaces. This product’s molecular weight ranges from 70,000 to 150,000 Da. It can be used in conjugation to methotrexate for increased drug transport. For Microencapsulation of islets. It is also used in simple, reproducible procedures for chromosomal preparations from various tissues. For immobilation of living cells in biocompatible semipermeable microcapsules. In the preparation of polycationic beads. Conjugation to albumin and horseradish peroxidase to enhance cellular uptake. Poly-lysine with mol. wt. >70,000 is useful in promoting cell adhesion to solid substrates.
