    Summary
    Thymosin beta4 is not cross-linked to many other proteins and its cross-linking to fibrin is competed by another family member, thymosin beta10.
  3. 03LabIn vitro (cell-free)Mechanism

    In cell-free assays, cross-linking of thymosin beta4 to fibrin was competed by thymosin beta10.

    In plain wordsIn lab tests, thymosin beta10 competed with thymosin beta4 for attachment to fibrin.

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.

    Summary
    After activation of human platelets with thrombin, thymosin beta4 is released and cross-linked to fibrin in a time- and calcium-dependent manner.

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

  2. 05LabEndogenous levelEx vivo tissueMechanism

    After thrombin activation of human platelets, released thymosin beta4 was cross-linked to fibrin in a time- and calcium-dependent manner.

    In plain wordsIn lab tests, the body's own thymosin beta4 released by activated human platelets attached to fibrin over time and needed calcium.
