Results from this study2

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

Studies that did not test the peptide alone2

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.

    In cultured calf and rat thymocytes, large thymocytes produced prothymosin alpha, which contains the thymosin alpha‑1 sequence, in a higher concentration than small thymocytes.

    In plain wordsIn lab cultures of calf and rat thymus cells, large cells made more of the thymosin alpha‑1 precursor than small cells.

    Summary · context
    Prothymosin alpha (ProT alpha), a polypeptide containing the sequence of thymosin alpha 1 (T alpha 1) at its NH2-terminus, has been isolated from calf thymocytes in a concentration in the order of that found in the whole thymic gland.

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

    In cultured calf and rat thymocytes, all subpopulations secreted prothymosin alpha with similar capacity, with 80-90% of the new polypeptide recovered from supernatants.

    Summary
    However, all the calf and rat thymocyte subpopulations show a similar capacity to secrete ProT alpha, the amount of the newly synthesized polypeptide recovered from cell culture supernatants being 80-90% of that found in thymocyte extracts.
