General description

Poly-L-arginine hydrochloride (PLA) is a homopolyamino acid. PLA enhances membrane permeability compared to poly-L-lysine. It has applications as drug carrier, neuroprotective agent and in anticancer vaccines preparations. Peptide vaccines in conjugation with PLA promotes antigen-presenting cells (APCs) to generate T cell and elicit immunostimulant functionality.

Application

Poly-L-arginine hydrochloride has been used:
  • to generate complex with stimulatory RNA isRNA9.2 as in neutrophils
  • used in ribosomal RNA transfection into human monocytic THP-1 cells
  • for coating alginate capsule beads

Quality

Contains 3% or less ornithine residue.

Analysis Note

Molecular weight based on viscosity of precursor poly-L-ornithine. Also assayed by MALLS.

Other Notes
