Anti-NXPH4 Antibody

Neurexophilin-4 (NXPH4) is a secreted neuropeptide-like glycoprotein that binds α-neurexins at presynaptic terminals, where it participates in the modulation of synaptic cell adhesion and neurotransmitter release. This unconjugated rabbit polyclonal reagent was raised against NXPH4 and validated for Western blot (WB) and immunohistochemistry (IHC) on human and rat tissue, making it useful for researchers mapping neurexin-associated signalling complexes in neuronal preparations.

The antibody is supplied as 100 µl of liquid in a vial and is recommended for storage at -20 °C in single-use aliquots to preserve activity across freeze-thaw cycles. Polyclonal reactivity against a native epitope profile gives broader recognition of isoforms than monoclonal alternatives, which is helpful when probing endogenous NXPH4 expression across brain regions and peripheral samples in developmental and synaptic plasticity studies.

Each lot is quality-controlled at Antibodies.com for the stated applications, and the unconjugated format allows the researcher to couple the primary antibody to HRP, biotin, or fluorophores according to the detection chemistry of their WB membrane or IHC staining protocol.
