sr-(s-Mussel Polypeptide-2 Pentapeptide-96 Cow Octapeptide-1 Lysine) is a single chain recombinant peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from s-Mussel Polypeptide-2, Pentapeptide-96, s-Cow Octapeptide-1, and Lysine. The fusion peptide contains 185 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
