VKGILS-NH₂（Cat No.:P000222）is a synthetic hexapeptide amidated at the C-terminus to enhance stability and bioactivity. Composed of valine, lysine, glycine, isoleucine, leucine, and serine, this short peptide sequence is studied for its structural simplicity and potential biological functions. The amidation reduces enzymatic degradation, prolonging activity in experimental systems. VKGILS-NH₂ has been explored as a model peptide in biochemical research, peptide-material interactions, and screening for bioactive motifs. Its amphiphilic nature may support applications in peptide design, drug delivery, and the investigation of peptide-receptor or peptide-membrane interactions.
