poly d lysine hydrobromide (mw 30000 70000)

Poly-D-lysine hydrobromide (MW 30000-70000) (Poly-D-lysine HBr) is an oral peptide CaSR agonist that eliminates proteinase K-resistant PrP from prion-infected SN56 neuroblastoma cells.

Poly-L-lysine hydrobromide (MW 150000-300000) is a lysine polymer that acts as a nonspecific cell attachment factor. It facilitates cell adhesion to solid substrates and can serve as a coating matrix for culture dishes and slides. Additionally, it exhibits anticancer activity against melanoma and lymphoma. Poly-L-lysine hydrobromide (MW 150000-300000) is also applicable in combination with hyperthermia, magnetic resonance imaging, and cancer cell detection.

Poly-L-lysine (hydrobromide) (MW 70000-150000) is a positively charged amino acid polymer serving as a non-specific cell adhesion factor. It exhibits excellent biocompatibility and enhances cell adhesion to solid substrates by increasing electrostatic interactions between the negatively charged cell membrane and the surface of the medium.

Poly-D-lysine hydrobromide (MW 150000-300000), is a synthetic polymeric substrate widely used in neural cell culture to enhance cell adhesion. Poly-D-lysine hydrobromide additionally functions as a calcium-sensing receptor (CaSR) agonist peptide, broadening its relevance in both cell biology and neurobiological research applications.
