Anti-DDX3Y Antibody

The DDX3Y gene encodes an ATP-dependent RNA helicase mapped to the AZFc interval of the human Y chromosome, with established roles in spermatogenesis and translational regulation. This unconjugated rabbit polyclonal reagent from Antibodies.com detects DDX3Y in Western blot workflows applied to human, mouse, and rat samples.

Supplied as 100 µl of a 1 mg/ml stock in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.3, the antibody is packaged in a single vial intended for repeated Western blot use. Working dilutions are titrated against individual lysate preparations, and the cross-species reactivity enables comparative work across rodent models and human specimens.

Because the reagent is polyclonal, it recognizes multiple epitopes across the DDX3Y target, an advantage when tracking expression shifts linked to spermatogenic failure or Y-linked gene dosage effects. The unconjugated format permits pairing with a secondary antibody of the researcher's choice for chemiluminescent or fluorescent immunoblot readouts. Intended for research use only.
