    Summary
    Functional studies revealed that recombinant Tβ4 stimulated angiogenesis via activation of the endothelial proteolytic systems, inhibition of endothelial cell adhesion, promotion of migration and capillary tube formation in Matrigel, and that its activity was similar to that observed for the synthetic 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
    The recombinant, non-glycosylated peptide was overexpressed in soluble form and purified by two-step immobilized metal ion affinity chromatography.
    1 context sentence
    Summary · context
    To overcome the high costs of solid phase synthesis, we developed a genetic engineering procedure of Tβ4 expression in a protease-deficient host strain, Escherichia coli BL21(DE3), transformed with different expression vectors (pRSETA, pET-15b and pEcoli-Cterm6 × HN).

    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).
