Results from this study2

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

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Other

    A peptide isolated from calf spleen was identified as thymosin alpha‑1, based on amino acid analysis, thermolysin digest and HPLC retention time.

    In plain wordsIn calves, the body's own thymosin alpha‑1 was found in the spleen.

    Summary
    A peptide isolated from calf spleen has been identified as thymosin alpha 1.
    1 context sentence
    Summary · context
    The identification was based on: 1) amino acid analysis; 2) thermolysin digest; and 3) retention time in two different HPLC systems.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    The amount of thymosin alpha‑1 isolated from calf spleen was 10-20% of that isolated from calf thymus glands.

    In plain wordsIn calves, the spleen held 10-20% as much of the body's own thymosin alpha‑1 as the thymus.
