Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human NUMB, different from the related mouse and rat sequences by one amino acid.
• Molecular weight context: reported MW: 71 kDa; calculated MW: 70804 MW
• Reactivity: Human,Monkey,Mouse,Rat
• Applications: Flow Cytometry, IHC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

Protein numb homolog; Protein numb homolog. Protein numb homolog is a protein that in humans is encoded by the NUMB gene. It is mapped to 14q24.2 to q24.3. The encoded protein, whose degradation is induced in a proteasome-dependent manner by MDM2, is a membrane-bound protein that has been shown to associate with EPS15, LNX1, and NOTCH1. The primary function of Numb in cell differentiation is as an inhibitor of Notch signaling which is essential for maintaining self-renewal potential in stem and progenitor cells. Numb also plays a crucial role in asymmetrical cell division during development, allowing for differential cell fate specification in the central and peripheral nervous systems. What’s more, the numb gene protein product controls binary cell fate decisions in the peripheral and central nervous systems of both invertebrates and mammals during neurogenesis. Functional note: Plays a role in the process of neurogenesis. Required throughout embryonic neurogenesis to maintain neural progenitor cells, also called radial glial cells (RGCs), by allowing their daughter cells to choose progenitor over neuronal cell fate. Not required for the proliferation of neural progenitor cells before the onset of neurogenesis. Also involved postnatally in the subventricular zone (SVZ) neurogenesis by regulating SVZ neuroblasts survival and ependymal wall integrity. May also mediate local repair of brain ventricular wall damage. Reported localization: Membrane; Peripheral membrane protein. Expression/tissue context: The expression of isoforms 1 and 2 does not seem to overlap. Isoform 1 is expressed by the blood vessels of different tissues. In the developing embryo it is found predominantly in the nervous system. In adult tissues, it is highly expressed in heart and placenta; moderately in lung, liver, skeletal muscle, kidney and pancreas; and low in adult brain. Isoform 2 is found in liver hepatocytes, kidney distal and proximal tubules.

Common research applications

• Western blotting: compare relative NUMB (Protein numb homolog) levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of NUMB (Protein numb homolog) across tissue regions and cell types using matched controls.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins
• Family / similarity context: Contains 1 PID domain.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
