Specificity / Sensitivity

TCF12/HEB (E5R8X) Rabbit mAb recognizes endogenous levels of total TCF12/HEB protein. Non-specific staining was observed in smooth and skeletal muscle by immunohistochemistry.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein corresponding to residues surrounding Asn450 of human TCF12/HEB protein.

Background

TCF12/HEB (T cell factor 12/HeLa E-box-binding protein) is a member of the E proteins that are type I basic helix-loop-helix domain-containing transcription factors that bind directly to the E-box DNA consensus sequence and control numerous developmental processes (1,2). E protein family members include E2A, E2-2, and TCF12/HEB. TCF12/HEB forms homo- or heterodimers with other E proteins to regulate transcription of target genes that play a critical role in the development of T cells, B cells, and plasmacytoid dendritic cells (2-4). The TCF12/HEB gene has two transcriptional start sites leading to the generation of the long form called HEBCan, and the short form, HEBAlt (5). The two isoforms are thought to have distinct functions, with HEBCan playing a role throughout T cell development, while HEBAlt functions in the efficient generation of T cell precursors (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
