Anti-bHLHe9 antibodies are used in antigen-specific immunodetection in biological samples. The target bHLHe9 is a known alias name of the protein neuronal PAS domain protein 2, encoded by the NPAS2 gene in humans. This 824-amino acid residue protein is reported to be a transcriptional activator, which forms a core component of the circadian clock. It is localized to the nucleus of the cell. Other synonyms for bHLHe9 include MOP4 and PASD4. Indicated applications for bHLHe9 antibodies listed below include Western Blot.
