About Thymalin
Thymalin is a polypeptide preparation obtained by mild acid extraction of calf thymus tissue, developed by Morozov and Khavinson as a thymic peptide bioregulator. It is a standardised low-molecular-weight polypeptide fraction rather than a single defined molecule, and in research is studied for effects on T-lymphocyte precursor differentiation and immune regulation.
For laboratory research use only. Not for human or veterinary use.
