Regulatory Status Legend
The R8-294 monoclonal antibody specifically binds to Neurogenic differentiation factor 1 (NeuroD1). NeuroD1 is a basic helix-loop-helix (bHLH) transcription factor that is also known as BHLHA3, Beta-cell E-box transactivator 2, BETA2 and NeuroD. NeuroD1 interacts with other bHLH proteins and binds the insulin E-box sequence to regulate pancreatic islet cell development. It also plays a key role in central nervous system (CNS) and sensory nervous system neuron development. Specifically, it is required for the terminal differentiation of neurons during late stages of neurogenesis in the CNS (cerebral cortex, hippocampus, and cerebellum) and the sensory nervous system (eye, inner ear, and olfactory system). During antibody development, the purified R8-294 monoclonal antibody was found to detect NeuroD1 by western blot and indirect immunofluorescent staining followed by flow cytometric analysis or imaging analysis.
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- Species testing during development may have been performed with a different format of the same clone. Selected applications have been tested for cross-reactivity.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- 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.
