Recombinant Human Defensin-α-1 is a 3.4kDa peptide comprised of 30 amino acid residues corresponding to full-length mature human defenstin alpha 1. Defensin-α-1, otherwise known as HNP-1, is a secreted cationic antimicrobial peptide and member of the alpha-defensin family, which plays an important role in the innate immune response against microbial infections.
