Opis ogólny

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.

Zastosowanie

  • 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]
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.

Działania biochem./fizjol.

Poly-L-lysine is a nonspecific attachment factor for cells useful in promoting cell adhesion to solid substrates by enhancing electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When it is absorbed to the cell culture surface, poly-L-lysine functions to increase the number of positively charged sites available for cell binding. With cells that can digest poly-L-lysine, poly-D-lysine should be used as the attachment factor.

Questions

1–10 of 12 Questions  
  1. Is the product P4707 suitable for coating glassware for cell culture? Also, what is the difference between Poly L and Poly D lysine?

    1 answer
    1. Yes, the product P4707 is suitable for coating glassware for cell culture. The difference between Poly L and Poly D lysine lies in their stereoisomeric properties. Poly-L-Lysine is a charge enhancer and can be used for coating many surfaces, including tissue culture plasticware and glassware. However, certain cells can digest poly-L-lysine, in which case the poly-D-lysine, such as P7405, should be used. This product can also be used to coat tissue culture plasticware and glassware.
