Advanced Biomatrix Poly-L-Lysine, Solution, 0.1 mg/mL

Poly-L-Lysine comes with 50 mL of a 0.1 mg/ml sterile-filtered solution. Poly-L-Lysine is a synthetic amino acid chain that is positively charged and widely used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces. This product’s molecular weight ranges from 70,000 to 150,000 Da yielding a solution viscosity for easy handling while providing sufficient binding sites for cell attachment. Poly-L-Lysine is a synthetic amino acid chain that is positively charged having one hydrobromide per unit of Lysine. This molecule has been used to culture a wide variety of cell types. Certain cell types secrete proteases, which can digest Poly-L-Lysine. For those cell types, Poly-D-Lysine, Catalog # 5049 should be used. Poly-L-Lysine surface coatings are designed to improve cell attachment, growth and differentiation of many cell types. Coated surfaces will often improve cell attachment in reduced or serum-free conditions.

Supelco Inc Poly-L-lysine solution 50ml

Poly-L-lysine coated glass coverslips have been used for mounting samples for scanning electron microscopy. Poly-L-lysine coated wells were used for trapping of PC-12 cells on electrodes. Poly-L-lysine-coated borosilicate glass slides were used for the seeding of viral vector-transduced cells. 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. 50ml
