Human Tb4 (Thymosin Beta 4) ELISA Kit

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Human Tb4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Tb4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human Tb4 in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Plays an important role in the organization of the cytoskeleton (PubMed:10848969, PubMed:1999398). Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization (PubMed:10848969, PubMed:1999398) , Potent inhibitor of bone marrow derived stem cell differentiation (PubMed:7694679). Acts by inhibits the entry of hematopoietic pluripotent stem cells into the S-phase (By similarity) [The Uniprot Consortium]
