Silkworm Rh-Polypeptide-47
Used in cosmetic products as skin conditioning, emollient, humectant and skin conditioning. Silkworm rh-Polypeptide-47 is a single chain recombinant human peptide, produced by silkworm after after using either a transient expression system or transgenesis (stable insertion of a copy of a human gene into its DNA). The starting gene is directly isolated from a human cell which codes for Collagen Alpha 1. It contains a maximum of 1464 amino acids, which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
