POLR3A Antibodies

AND POLR3A ELISA kits, POLR3A Proteins

Many biological assays use antibodies to detect POLR3A, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with POLR3A in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop POLR3A antibodies...

We validate the specificity of these antibodies to POLR3A by testing them on tissues known to express POLR3A positively and negatively. Browse below to find the POLR3A antibody that suites your experiment. We have 3 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.

POLR3A Overview

Facts about DNA-directed RNA polymerase III subunit RPC1.

POLR3A 3D structure. Source: alphafold

DNA-directed RNA polymerase III subunit RPC1 (POLR3A)

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic core component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs.

Forms the polymerase active center together with the second largest subunit. A single-stranded DNA template strand of the promoter is positioned within the central active site cleft of Pol III.
