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. It has also been used as a transfection agent for efficient labeling and to facilitate endocytosis. 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.

Poly-L-lysine hydrobromide is a nonspecific attachment factor in promoting cell adhesion to the substratum.
