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.

    The [D-Arg30]prothymosin alpha fragment 1-30 analog retained activity on the impaired blastogenic response of T-lymphocytes from uremic patients.

    In plain wordsIn lab tests on immune cells, the modified fragment kept its activity.

    Summary · context
    Deacetyl-thymosin alpha 1, a synthetic octaeicosapeptide corresponding to deacetyl-prothymosin alpha fragment 1-28, has restoration ability for the impaired blastogenic response of T-lymphocytes of uremic patients but is susceptible to proteolytic digestion
    Summary · context
    A fragment analog, [D-Arg30]prothymosin alpha fragment 1-30, containing D-arginine in place of arginine residue at position 30 was synthesized by the liquid phase procedure and studied for immunological effect on the impaired blastogenic response of T-lymphocytes isolated from uremic patients after…

    In human serum, the [D-Arg30]prothymosin alpha fragment 1-30 analog was highly stable, whereas deacetyl-thymosin alpha‑1 is susceptible to proteolytic digestion.

    In plain wordsIn lab tests, the modified fragment stayed intact in human serum, while deacetyl-thymosin alpha‑1 breaks down more easily.
