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 beta-4 (human) 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 beta-4 (human).

  1. 01LabNot a test of Thymosin beta-4 (human) aloneIn vitro (cell-free)Activity measurement

    In cell-free assays with rabbit muscle actin, the sea urchin peptide needed about twice the concentration of thymosin beta‑4 to inhibit actin polymerization or nucleotide exchange equally.

    In plain wordsIn lab tests, a sea urchin peptide bound actin more weakly than thymosin beta‑4. It needed about twice the concentration for the same effect.

    Summary
    The affinity of the sea urchin peptide for rabbit muscle actin is apparently lower than that of thymosin beta4, since about twice the concentration of sea urchin peptide is required to give inhibition of actin polymerization or nucleotide exchange equivalent to thymosin beta4.

    In this study, Thymosin beta-4 (human) 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 beta-4 (human).

    Summary
    The sequences of the scallop and sea urchin beta-thymosins are 80% identical to each other, 75% identical to residues 1-40 of thymosin beta4, and 72-80% identical to residues 1-40 of other vertebrate beta-thymosins.

    In this study, Thymosin beta-4 (human) 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 beta-4 (human).
