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

Studies that did not test the peptide alone3

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)Mechanism

    In a cell-free assay with tissue transglutaminase, glutamine residues at positions 23 and 36 of thymosin β4 were labeled with the cross-linker cBED.

    In plain wordsIn lab tests, a chemical tag attached to two sites on thymosin β4.

    Summary
    By high-resolution HPLC/ESI-MS (electrospray ionization-mass spectrometry) and tandem MS (MS/MS) of the trypsin digest, it was established that glutamine residues at positions 23 and 36 were labeled, whereas Q39 showed no reactivity.

    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).

  2. 02LabNot a test of Thymosin beta-4 (human) aloneIn vitro (cell-free)Mechanism

    In a cell-free assay, the glutamine at position 39 of thymosin β4 showed no reactivity with cBED.

    In plain wordsIn lab tests, the chemical tag did not attach to a third site on thymosin β4.

  3. 03LabNot a test of Thymosin beta-4 (human) aloneIn vitro (cell-free)Activity measurement

    In a cell-free setting, covalent binding of cBED to thymosin β4 did not influence its G-actin sequestering activity.

    In plain wordsIn lab tests, attaching the chemical tag did not change the ability of thymosin β4 to bind G-actin.
