Product Information

• Name: Serum Thymic Factor
• Synonyms: Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn, Thymulin, (formerly: Facteur Thymique Serique (FTS))
• Brand: Biosynth
• Description: Serum thymic factor (STF) is a peptide that is secreted by the thymus gland. STF has been shown to inhibit the binding of lysosomal enzymes to their receptors in the presence of proteinase inhibitors. STF also activates complement C3 and C4, leading to the production of anaphylatoxins. This peptide has been used as a research tool for studying protein interactions and receptor-ligand interactions. Additionally, STF has been shown to be a ligand that binds to a receptor on human erythrocytes.
