Anti-NK-4R Antibody

Raised in rabbit, this unconjugated polyclonal antibody targets the neurokinin-4 receptor (NK-4R), a G protein-coupled receptor encoded by TACR4 and involved in tachykinin-mediated signaling pathways. Distributed by Antibodies.com, the reagent is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, formatted as a 100 µl vial for Western blot workflows.

The polyclonal host response yields recognition of multiple epitopes on the NK-4R target, supporting band detection across species. Reactivity is validated for human, mouse, and rat samples, allowing comparative studies in tissue lysates and cell-line models.

For Western blot applications, working dilution should be titrated empirically because optimal antibody concentrations depend on antigen abundance and transfer conditions. The unconjugated format permits downstream conjugation to HRP, biotin, or fluorophores, giving laboratories control over detection chemistry.

Storage recommendations call for aliquoting on receipt and freezing at -20 °C or colder; repeated freeze-thaw cycles should be limited to preserve antibody integrity. Sodium azide at 0.1% protects against microbial contamination during routine benchtop use, though samples should be washed if downstream protocols require azide-free conditions.
