Anti-Hox-B4 (A135) Antibody

A rabbit polyclonal antibody targeting the Hox-B4 homeobox transcription factor, formulated for immunohistochemistry on human and mouse tissue sections. Each vial contains 50 µl of antibody at 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2, supplied by Antibodies.com as an unconjugated primary reagent ready for use with user-selected detection systems.

HOXB4 is a developmental regulator implicated in hematopoietic stem cell maintenance and embryonic patterning, making this reagent relevant to stem cell biology, hematopoiesis, and developmental gene expression studies. The polyclonal format presents multiple epitopes across the target protein, useful when probing conserved homeodomain regions, while the rabbit host provides an alternative to mouse monoclonals and helps limit endogenous immunoglobulin background in mouse tissue. Validated reactivity is reported for Human and Mouse samples, supporting comparative work across species.

The unconjugated format lets researchers pair the antibody with HRP, biotin, or fluorophore-labeled secondary reagents of choice for chromogenic or immunofluorescence protocols. The PBS-based formulation with sodium azide preservative can be added directly to standard IHC buffers, and aliquoting is recommended to limit freeze-thaw cycles and preserve reagent activity across multiple staining runs.
