Application

Poly-L-lysine solution has been used for the attachment of endothelial cell cross sections to UV-crosslinked PET membrane frame slides. Poly-L-lysine coated slides were used for the placement of tissue sections for immunohistochemical assay.
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.

Biochem/physiol Actions

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.

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.

Preparation Note

This product is supplied as a 0.10% (w/v) solution in water. Coating slides with this solution should be followed with a 5 minute incubation and drying the slides at room temperature. Coated slides will be stable for one year if protected from dust.

The Human Protein Atlas Program has carefully selected three different human cell lines, A-431 epidermoid carcinoma, U-251 MG glioblastoma and U-205 osteosarcoma, for organelle mapping of the proteome. As Prestige Antibodies are studied by immunofluorescence (IF) staining, three well-characterized organelle markers for nuclei, microtubules and endoplasmic reticulum are used correspondingly as specific probes. The high-resolution confocal images are annotated based on sub-cellular localization. In addition, staining intensity and characteristics are also part of an overall assessment as well as comparison to literature (if available).
