Anti-NPAS4 Antibody

NPAS4 is a brain-enriched neuronal PAS domain transcription factor that is rapidly induced by synaptic activity, and this polyclonal reagent from Antibodies.com is raised in rabbit to detect both human and mouse NPAS4 by Western blot (WB). The antibody is supplied as 100 µl at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.3, and is unconjugated to permit flexible downstream labeling with secondary reagents of the researcher's choice.

Reactivity is confirmed against human and mouse NPAS4, supporting detection in lysates prepared from primary neuronal cultures, hippocampal tissue, and other brain regions. Because NPAS4 expression rises with neuronal firing, the reagent supports studies of activity-dependent transcription, long-term memory formation, excitatory-inhibitory balance, and in models of ischemia, seizures, and addiction. The unconjugated IgG format pairs with commonly used anti-rabbit HRP, alkaline phosphatase, or fluorescent secondaries.

Storage in the original vial under refrigerated conditions preserves activity; aliquoting upon first use limits freeze-thaw cycles. Provided as a single use liquid reagent for routine immunoblotting workflows.
