SCIENTIFIC OVERVIEW
Scientific background and research classification for this laboratory reference material.
Thymalin is supplied as a synthetic thymic nonapeptide whose governed molecular identity is thymulin (serum thymic factor), pGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn. CAS 63958-90-7; molecular formula C33H54N12O15. The N-terminal residue is pyroglutamate (pGlu; also written '<Glu' or 'Pyr'), and the C-terminus is a free acid. It is supplied as a lyophilized peptide reference material for laboratory research use only.
In this catalog, 'Thymalin' is the supplier/material designation for this defined thymic nonapeptide (scientifically 'thymulin'); it is provided as a single synthetic peptide reference standard rather than a thymic tissue extract.

Mechanism of Action
Molecular interaction profile describing how this research material engages receptor systems and influences downstream biological signaling pathways.
Thymulin is a zinc-dependent thymic peptide: its biologically active form is the zinc-bound nonapeptide, and zinc binding has been linked to the conformational epitope associated with its lymphocyte-differentiating activity (Dardenne et al., 1985). It is studied for roles in T-lymphocyte differentiation and immunoregulation. No cloned or characterized receptor for thymulin is represented in the governed molecular-target vocabulary, and zinc functions here as a biological cofactor rather than a governed target; the governed molecular-target and pathway fields are therefore left empty by design, and the governed formula represents the apo-peptide.
