  • rh-Polypeptide-20 is a single chain recombinant human peptide, produced by fermentation in E. coli. The starting gene is directly isolated from a human cell which codes for C-C Motif Chemokine 25 used as such or adapted to the production host. It contains a maximum of 150 amino acids which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
