Results from this study1

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone1

In this study, Thymosin alpha-1 was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin alpha-1.

    A 16,000-dalton polypeptide coded by purified calf thymus mRNA contains amino acid sequences corresponding to residues 11-18 and 19-25 of thymosin alpha‑1.

    In plain wordsIn lab tests, a larger protein made from calf thymus genetic material contains parts of the thymosin alpha‑1 sequence.
