Anti-NUMB (h Numb, h-Numb, Numb Homolog, Numb Protein Homolog, Protein S171, S171)

Numb is an evolutionarily conserved membrane-associated protein. It exists in four isoforms that differ in two functional domains: a phosphotyrosine-binding (PTB) domain and a proline-rich region (PRR). It plays a role in the control of cell fate decisions during development and antagonizes the actions of Notch. Numb proteins appear to control the self-renewal of all neural progenitor cells and could possibly play similar roles in stem-cell maintenance in other tissues. Cellular Localization: Membrane-associated , Applications: , Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
