Anti-E4BP4 Antibody

This rabbit polyclonal antibody from Antibodies.com targets E4BP4, also known as NFIL3 (Nuclear Factor, Interleukin-3 Regulated), a basic leucine zipper transcription factor with roles in NK cell maturation, cytokine-driven lymphocyte differentiation, and circadian rhythm control. The unconjugated reagent is supplied as 100 µl of a 1 mg/ml stock in PBS with 0.1% Sodium Azide and 50% glycerol, ready for dilution into standard immunodetection workflows.

Validated for Western blot, immunohistochemistry, and immunofluorescence on human samples, the polyclonal format offers broader epitope coverage than monoclonal alternatives and is well suited to probing endogenous E4BP4/NFIL3 expression across cell lines and primary tissue. Researchers working on innate immune signaling, Th cell polarization, and transcription factor networks rely on this reagent to map E4BP4-driven regulatory circuits.

For best results, store the vial at -20°C in small aliquots to limit freeze-thaw cycles and protect from light because of the azide preservative. The buffer formulation is compatible with common HRP-conjugated secondary antibodies and standard fluorescence detection systems used in WB, IHC, and IF protocols.
