Thymalin (Thymulin / Serum Thymic Factor) – Zinc-Dependent Nonapeptide | Research Use Only

Thymalin, commonly associated with the well-characterized nonapeptide Thymulin (also known as Serum Thymic Factor, FTS, or Nonathymulin), is a thymus-derived peptide complex referenced in immunological research literature.

The defined synthetic nonapeptide form represents a specific sequence identified within thymic peptide research. Natural thymic extracts described as “Thymalin” may consist of heterogeneous peptide fractions.

Research Use Only: This material is supplied strictly for laboratory developmental research use. It is not intended for human or veterinary consumption.
