Preparation And Storage
Recommended Assay Procedures
The 24B72D11.1 antibody is recommended for western blot analysis (0.5-2.0 µg/ml). Rat embryonic brain can be used as a positive control. Neuro2A mouse neuroblastoma cells (ATCC CCL-131) may also be used as a positive control for this application.

The 24B72D11.1 antibody is reported in the literature to work well for immunohistochemistry. Immunohistochemistry: For more detailed information please refer to the cited journal references and http://www.bdbiosciences.com/support/resources/cell_biology/index.jsp
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
MASH1 and MASH2 (Mammalian achaete-schute Homolog 1 and 2) are basic helixloop-helix transcription factors which are mammalian homologs of the achaete-schute gene family that is required for neuronal development in Drosophila. The bHLH motif is present in many types of transcription factors including E2-2, E47, MyoD and others. MASH1 has been shown to heterodimerize with other bHLH containing transcription factors. MASH1-E12 heteromers bind to and promote transcriptional activation of muscle creatine kinase, a known target for MyoD activation. However, MASH1 appears to play its primary role during early development of the autonomic nervous system. In committed neuronal precursor cells, early expression of MASH1 activates a subset of neuron-specific genes to promote differentiation. Thus null mutations in the MASH1 gene suggest that MASH1 is a valuable marker for investigation of neural development in mammals. MASH1 is observed as an ~34 kDa protein by SDS-PAGE.
