Anti-POLR2J1 Antibody

Raised in rabbit, this polyclonal reagent from Antibodies.com targets POLR2J1, the shared subunit h of RNA polymerase II that is also incorporated into RNA polymerases I and III and is required for accurate transcription of protein-coding genes. Supplied unconjugated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is provided as a 100 µl liquid that is ready to dilute for downstream immunoblotting and microscopy workflows.

Validated for western blot, immunohistochemistry, and immunofluorescence, the antibody detects the human, mouse, and rat POLR2J1 protein and supports studies of transcriptional regulation, mRNA biogenesis, and the reported association between POLR2J1 expression and tumor cell proliferation. The 50% glycerol buffer stabilizes the protein during frozen storage and helps limit damage from repeated freeze-thaw cycles, while the 0.1% sodium azide component preserves diluted working aliquots held at refrigerated temperature for routine benchtop use.
