Anti-FBL Antibody

Raised in rabbit and purified by affinity chromatography against a recombinant human FBL immunogen, this polyclonal reagent from Antibodies.com targets fibrillarin (FBL), a highly conserved nucleolar protein widely used as a marker for the nucleolus and for studies of ribosomal RNA processing. The antibody is supplied as an unconjugated liquid at 1.0 mg/ml in a 50 µl format, and it has been validated for Western blotting (WB), immunohistochemistry (IHC) and immunofluorescence (IF), covering the core workflows used to localize fibrillarin in fixed cells and to detect the endogenous ~34–37 kDa band in lysates. The host species is rabbit, the clonality is polyclonal, the isotype is IgG, and the conjugate is unconjugated, leaving the antibody ready for direct labelling or pairing with secondary reagents of the researcher's choice. Cross-reactivity has been confirmed in human, mouse and rat samples, making it suitable for comparative studies across the most commonly used mammalian model systems, and the reagent is intended for research use only. As with all Antibodies.com primary antibodies, it should be stored according to the manufacturer's recommendations (typically short-term at 2–8 °C and long-term in aliquots at –20 °C) to preserve activity across multiple experiments.
