Anti-RPS4X Antibody

Produced by Antibodies.com, this rabbit polyclonal reagent targets ribosomal protein S4 X-linked (RPS4X), a core component of the 40S small ribosomal subunit that is essential for cytoplasmic translation. Supplied as an unconjugated 100 µl volume, the antibody recognizes the human, mouse, and rat forms of the target, supporting comparative work across cultured mammalian cells, primary tissue, and animal-model systems.

Validated applications include western blot for resolving endogenous RPS4X in whole-cell lysates and tissue extracts, and immunofluorescence for visualizing subcellular distribution, where the protein shows characteristic cytoplasmic and nucleolar localization consistent with its role in ribosome assembly and protein synthesis. Because RPS4X is encoded on the X chromosome and has a Y-linked paralog (RPS4Y), the reagent is widely used in studies of sex-chromosome dosage, Turner syndrome research, and investigations of ribosomal protein haploinsufficiency. RPS4X detection has also been reported in cancer research contexts where ribosome biogenesis is dysregulated.

Format details: polyclonal, unconjugated, rabbit host, 100 µl volume. For handling, aliquot upon arrival, store refrigerated, and protect from light to preserve stability across freeze-thaw cycles. This reagent is intended for research use only and is validated for in vitro applications.
