Chromatin IP 1:50

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

POLR3A (D5Y2D) Rabbit mAb recognizes endogenous levels of total POLR3A protein.

Species Reactivity:

Human, Mouse, Rat, Monkey

Species predicted to react based on 100% sequence homology

Bovine, Dog, Guinea Pig

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val613 of human POLR3A protein.

Background

POLR3A is the largest subunit of the DNA-dependent RNA polymerase III, one of the DNA-dependent RNA polymerases that transcribe small non-coding RNAs such as the 5S rRNA, tRNAs and some miRNAs (1-3). Together with the second largest subunit, POLR3A forms the catalytic center of the polymerase (4). In addition, RNA polymerase III plays a role in the innate immune response by sensing non-self double stranded DNA. Transcription of the non-self DNA into RNA induces type I interferon production through the RIG-I pathway (5,6). Studies suggest that mutations in the POLR3A gene may be linked to hypomyelinating leukodystrophies; a group of inherited neurodegenerative disorders (7-9).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
