Scientific Data Images for Human TCF-3/E2A Antibody
Detection of Human TCF-3/E2A by Western Blot.
Western blot shows lysates of Jurkat human acute T cell leukemia cell line. PVDF Membrane was probed with 2 µg/mL of Human TCF-3/E2A Monoclonal Antibody (Catalog # MAB44062) overnight at 4oC followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for TCF-3/E2A at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human TCF-3/E2A Antibody

Background: TCF-3/E2A
TCF-3, also known as E2A and ITF-1, is a member of the E protein homeobox family. TCF-3 regulates checkpoints that allow B lineage commitment and B and T cell receptor gene rearrangement. Two isoforms named E12 and E47 are alternatively spliced within the DNA binding and HLH domain. The region of human TCF-3 used as the immunogen, which is identical for E12 and E47, shares 80% and 79% aa identity with mouse and rat TCF-3, respectively.
