Results from this study1

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

Studies that did not test the peptide alone1

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).

    Summary · context
    Matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI) hybrid quadrupole time-of-flight (Qq-TOF) were used to analyze the precipitated and extracted endogenous peptides from fetal calf serum.

    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).
