| Background | Numb is a transmembrane signaling receptor that is activated by the DSL family of ligands. Studies suggest that mammalian Numb plays a role in progenitor cell fate in neurogenesis. Numb exerts its role on cell fate by antagonizing Notch signaling. The mammalian Numb gene undergoes alternative splicing to produce at least four functionally different Numb isoforms which regulate different pro...cesses. A loss of Numb expression has been demonstrated in breast cancer, non-small cell lung cancer and chronic myelogenous leukemia. Show More |

| Application Notes | In WB one may see any or all of the four isoforms. The molecular weight of human and mouse NUMB is 72 kDa (isoform 1), 66 kDa (isoform 2), 71 kDa (isoform 3), and 65 kDa (isoform 4). Multiple non-specific bands may be seen with lower dilutions and/or longer exposure times than suggested in the protocol we used to obtain our data. In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue. |
