Anti-HNRNPA3 Antibody

This polyclonal reagent from Antibodies.com targets HNRNPA3 (Heterogeneous Nuclear Ribonucleoprotein A3), a nucleic acid-binding protein central to pre-mRNA splicing, mRNA stability, and translational control in human cells. Raised in rabbit and purified as an IgG preparation, the antibody is supplied unconjugated in a 200 µl vial and is validated for Western Blot detection of the human target.

HNRNPA3 has attracted research interest as a candidate biomarker and post-transcriptional regulator in hepatocellular carcinoma, lung adenocarcinoma, and other solid tumors where dysregulated RNA processing contributes to disease progression. Investigators studying stress granule assembly, alternative splicing programs, or the composition of hnRNP complexes can apply this antibody to probe endogenous expression in whole-cell lysates and fractionated nuclear extracts. The unconjugated format gives flexibility in pairing with HRP- or fluorophore-conjugated secondary antibodies matched to a chosen detection platform.

For best stability, store at -20°C in working aliquots and limit repeated freeze-thaw cycles. Centrifuge briefly before opening the vial. For research use only.
