Overview
About Thymalin / Thymulin.
Thymalin is a low-molecular-weight polypeptide fraction extracted from calf/bovine thymus and one of the Khavinson-class peptide bioregulators studied for thymic-immune modulation, whereas Thymulin (serum thymic factor / FTS) is a chemically defined zinc-dependent nonapeptide studied as a thymic epithelial hormone in T-cell differentiation. The two are distinct materials — an extract mixture versus a single defined peptide — grouped by shared research context rather than identical chemistry.

FAQ
Thymalin / Thymulin — frequently asked by B2B buyers.
Are Thymalin and Thymulin the same compound?
No. Thymalin is a low-molecular-weight polypeptide fraction isolated from calf/bovine thymus — a defined-process extract rather than a single molecule. Thymulin (serum thymic factor, CAS 63958-90-7) is a chemically defined, zinc-dependent nonapeptide. They share a thymic-immune research context but are distinct materials; specify which you require on your RFQ.
What vial sizes and minimum order quantity are available?
Standard vials are offered at 10 mg and 20 mg, with a minimum order quantity of 50 kits (500 vials). Alternative fill weights, bulk lyophilized powder, and private-label / OEM packaging are available on request.
What documentation ships with each batch?
Each lot ships with a Certificate of Analysis reporting HPLC purity and mass-spectrometry identity confirmation. For the defined Thymulin nonapeptide, MS confirms the 858.85 g/mol target mass; for Thymalin extract, batch and process documentation is provided in place of a single-molecule mass. Additional analytical data is available on RFQ.
Is the material synthetic or animal-derived?
Thymulin is manufactured by solid-phase peptide synthesis. Thymalin is traditionally a bovine/calf-thymus polypeptide fraction; sourcing, origin, and process documentation are provided per batch, and synthetic or defined-peptide alternatives can be quoted on request.
How is the material labeled and shipped for compliance?
Both are supplied as lyophilized powder with cold-chain or insulated packaging as needed, and all material is labeled for research and laboratory use only — not for consumer or veterinary use. Buyers are responsible for import clearance and regulatory compliance in their jurisdiction; supporting documentation is available to facilitate customs.
