| Description | EPQpYEEIPIYL, a phosphopeptide, is a Src homology 2 (SH2) domain ligand. EPQpYEEIPIYL activates Src family members (e.g. Lck, Hck, Fyn) by binding to SH2 domains[1][2] | Apo-Bovine Transferrin refers to iron free Transferrin (HY-P3267), serves as Transferrin receptor ligand and mediates iron release from endothelial cells. Apo-Transferrin indicates an iron deficient environment, can directly bind to hephaestin, which can convert Fe2+ to Fe3+. Apo-Transferrin Apo-Bovine Transferrin refers to iron free Transferrin (HY-P3267), serves as Transferrin receptor ligand and mediates iron release from endothelial cells. Apo-Transferrin indicates an iron deficient environment, can directly bind to hephaestin, which can convert Fe2+ to Fe3+. Apo-Transferrin mediates iron efflux most likely in cooperation with ferroportin 1[1]... Read More | Palmitoyl tetrapeptide-20 (PTP20) is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC50: 0.16 nM), enhancing catalase activity to reduce H2O2 accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 (PTP20) is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC50: 0.16 nM), enhancing catalase activity to reduce H2O2 accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 can be used in research on preventing hair loss and improving hair graying[1]... Read More | Peptide T is an octapeptide from the V2 region of HIV-1 gp120. Peptide T is a ligand for the CD4 receptor and prevents binding of HIV to the CD4 receptor | Streptavidin is a ~60 kDa homotetramer. Streptavidin binds four molecules of biotin with the highest affinity. The binding affinity of biotin to streptavidin is one of the highest reported for a non-covalent interaction to date, with a KD ~0.01 pM[1]. Streptavidin has an immunosuppressive role[2].
