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. 01LabEndogenous levelIn vitro (cells)Other

    In chick embryo fibroblast extracts, most G-actin was detected as a complex with the cells' own Tbeta4.

    In plain wordsIn chick cells, most of the cells' own free actin was bound to the cells' own thymosin beta4.

    Summary
    Fibroblast extracts are analyzed by non-denaturing polyacrylamide gel electrophoresis and immunoblotting where most of the G-actin is detected as a complex with Tbeta4.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.

  2. 02LabEndogenous levelIn vitro (cells)Other

    In chick embryo fibroblast extracts, most G-actin eluted in a peak that also contained the cells' own Tbeta4 at an overall molar ratio of 1.9:1 relative to actin.

    In plain wordsIn chick cells, the cells' own thymosin beta4 was present at about 1.9 parts per part of actin in the main actin peak.

    Summary
    When fibroblast extracts are fractionated by gel filtration and the fractions are analyzed by PAGE and HPLC, most of the G-actin elutes in a peak that also contains Tbeta4 at an overall molar ratio of 1.9:1 relative to actin.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.
