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.

  1. 01LabNot a test of Thymosin alpha-1 aloneEx vivo tissueActivity measurement

    In rat thymocytes, a polypeptide fraction of about 3 K from thymic epithelial cell supernatant gave non-rosette-forming cells rosette-forming capacity.

    In plain wordsIn lab tests with rat cells, a small polypeptide fraction made thymus cells able to form rosettes.

    Summary
    One of the polypeptide fractions (estimated molecular weight: 3 K) possessed the activity endowing non-RFC with rosette-forming capacity.
    1 context sentence
    Summary · context
    Since its molecular weight was similar to that of thymosin alpha 1, the fraction was pretreated with anti-thymosin alpha 1 antiserum.

    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.

  2. 02LabNot a test of Thymosin alpha-1 aloneEx vivo tissueActivity measurement

    Pretreating the active fraction with anti-thymosin alpha‑1 antiserum suppressed its rosette-inducing activity.

    In plain wordsIn lab tests, an antibody against thymosin alpha‑1 blocked the activity of the fraction.
