POLR2B antibody (pAb) tested by Immunoprecipitation.
10 µl of POLR2B antibody was used to immunoprecipitate POLR2B from 200 µg of HEK293 nuclear cell extract (lane 2). 10 µl of rabbit IgG was used as a negative control (lane 1). The immunoprecipitated protein was detected by Western blotting using the POLR2B antibody at a dilution of 1:500.

for POLR2B antibody (pAb)Background

POLR2B (polymerase (RNA) II (DNA directed) polypeptide B, 140 kDa) DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB2 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template (By similarity).

for POLR2B antibody (pAb)Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.

for POLR2B antibody (pAb)Guarantee

This product is guaranteed for 6 months from date of receipt.

This product is for research use only and is not for use in diagnostic procedures.
