Sr-Hydrozoan Polypeptide-1

What is it?

sr-Hydrozoan Polypeptide-1 is a single chain recombinant protein fragment produced by fermentation in E. coli. The starting gene is synthesized to be identical to the gene which codes for Fibrillar Collagen derived from Podocoryna carnea (hydrozoan). The parent protein contains a maximum of 429 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
