Abstract:
The human neuregulin 1-beta1 (NRG1-beta1, amino acid residues 176-246) was chemically synthesized by Fmoc-based solid phase peptide synthesis (SPPS) followed by folding in a redox buffer. The biological activity of the synthesized NRG1-beta1 was confirmed by ligand-induced tyrosine phosphorylation on Chinese hamster ovary (CHO) cells expressing ErbB-4.
