Anti-PP32R1 Antibody

This rabbit polyclonal antibody from Antibodies.com is raised against PP32R1, a leucine-rich acidic nuclear phosphoprotein of the ANP32 family that contributes to chromatin regulation and histone chaperone activity in human cells. The reagent is supplied as an unconjugated 100 µL polyclonal antiserum intended for detection of the human PP32R1 target.

Validated for Western blot and ELISA workflows, the antibody is reactive with human samples and supports expression profiling of ANP32 family members, comparative immunoblot studies in tumor-derived and normal cell lines, and immunodetection of PP32R1 in recombinant protein preparations. PP32R1 has been investigated as a context-dependent modulator of protein phosphatase 2A and histone acetyltransferase complexes, making immunoblot-based readouts helpful for examining its abundance and interaction partners across model systems.

The unconjugated format allows flexible pairing with HRP, biotin, or fluorophore-conjugated secondary antibodies, enabling chemiluminescent, colorimetric, or fluorescent readout depending on the assay design. For routine handling, follow standard polyclonal antiserum practice: refrigerate the working aliquot and freeze the stock in single-use portions to limit freeze-thaw cycles and preserve antibody titer.
