What Thymosin Alpha 1 is
Thymosin Alpha 1 (thymosin alpha-1, Tα1) is a 28-amino-acid peptide with an acetylated N-terminus. It was first isolated from thymus tissue, in the preparation known as thymosin fraction 5, and is cleaved from a larger precursor protein, prothymosin alpha. The material supplied here is synthetic and lyophilised, for in-vitro laboratory research; sequence, molecular mass and CAS number are listed in the specifications table.
Research context
The published research literature on Thymosin Alpha 1 includes work on immune signalling, host-pathogen response models, cell proliferation and oncology models, epithelial ion-transport models, and adjuvant or broader immune-response studies.
