At least four isoforms of NUMB are known to exist, this antibody will detect all of them.
Purification
NUMB Antibody is affinity chromatography purified via peptide column.
Immunogen
NUMB antibody was raised against a 17 amino acid synthetic peptide near the carboxy terminus of human NUMB. The immunogen is located within the last 50 amino acids of NUMB.

Background
NUMB Antibody: NUMB, the mammalian homolog to the Drosophila asymmetric cell fate determinant NUMB, is thought to share several features molecular mechanisms in mammalian cells, generating asymmetric cell divisions during neurogenesis in vertebrate development as well as in hematopoietic stem cells. NUMB has been shown to inhibit Notch signaling, and is itself regulated by ubiquitinylation by MDM2. NUMB has also been shown to help activate the tumor suppressor p53, suggesting that loss of NUMB in cancerous cells would not only activate the potential oncogene Notch, but diminish the tumor suppressing effect of p53.
