Escherichia Coli Extract/sr-(Methionyl Deca-(Sh-Polypeptide-50 Leucyl Sh-Polypeptide-50 Arginyl Sh-Polypeptide-138))

¿Qué es?

Escherichia Coli Extract/sr-(Methionyl Deca-(sh-Polypeptide-50 Leucyl sh-Polypeptide-50 Arginyl sh-Polypeptide-138)) is a single chain recombinant peptide, produced by fermentation in E. coli, where the final product contains proteins from the E. coli host. The starting gene is synthesized by the fusion of ten copies of the genes of sh-Polypeptide-50, Leucine, Arginine, and sh-Polypeptide-138, with the initiation code for methionine. The fusion peptide contains 391 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
