Anti-PIWIL4 Antibody - Identical to Abcam (ab180867)

PIWIL4 (also called HIWI2) is a germline-enriched Argonaute-family protein required for piRNA-directed transposon silencing, maintenance of genomic integrity in germ cells, and is re-expressed in multiple somatic tumour types. This unconjugated rabbit polyclonal IgG reagent is raised against PIWIL4 and validated for western blot, immunohistochemistry, and immunofluorescence applications across human, mouse, and rat samples, supplied by Antibodies.com in a 100 µL vial. It is offered as a research-use-only primary antibody suited to studies of piRNA pathway function, spermatogenesis, germline and stem cell biology, and PIWIL4 expression profiling in cancer cell lines and tissue sections. The unconjugated format allows pairing with HRP-, biotin-, or fluorophore-conjugated secondary reagents of the researcher's choice.

For western blot, run reduced lysates on SDS-PAGE and transfer to PVDF or nitrocellulose; for IHC, optimise antigen retrieval per tissue; for IF, detect with standard anti-rabbit fluorophore conjugates. Store at -20 °C in working aliquots to limit freeze-thaw cycles, and protect from light when handling fluorescent secondaries. The 100 µL pack size is intended for research use only and is not for diagnostic procedures.
