Thymosin Alpha-1 (TA-1) – Research Peptide Overview
Thymosin Alpha-1 (TA-1): Research Peptide Overview
Thymosin Alpha-1 (Tα1) is a 28-amino-acid peptide first isolated from thymus tissue in the 1970s. It is a research peptide studied in in-vitro and animal models of immune-cell signaling.
What is Thymosin Alpha-1?
Thymosin Alpha-1 is a synthetic version of a naturally occurring thymic peptide. In the laboratory it is used to study signaling mechanisms in in-vitro and animal models.
Mechanisms Studied in Laboratory Models
