Nicotiana Benthamiana Hexapeptide-40 sh-Oligopeptide-1 is a fusion peptide of Hexapeptide-40 with a single chain recombinant human peptide, produced by Nicotiana benthamiana after transformation with either a transient expression system or transgenesis (stable insertion of a copy of a human gene into its DNA). The starting gene is synthesized to be identical to the human gene which codes for Epidermal Growth Factor, and contains a maximum of 1207 amino acids. The fusion peptide contains 59 amino acids, which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
