No. :BS4246

Product Name :Rpb1 (phospho-S1619) polyclonal antibody（KU）

Swiss-Prot :P24928

Host :Rabbit

Reactivity :Human,Mouse,Rat

Applications :WB IHC

Application_all :WB: 1:500~1:1000 IHC: 1:50~1:200

Background :RPB1 is a subunit of RNA polymerase II which catalyses transcription of RNA from DNA. RPB1 forms the polymerase active center together with the second 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. RPB1 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.

Product :Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2

Purification&Purity :The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).

Storage&Stability :Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.

Specificity :p-Rpb1 (S1619) polyclonal antibody detects endogenous levels of Rpb1 protein only when phosphorylated at Ser1619.

BiowMW :~ 280 kDa

Note :For research use only, not for use in diagnostic procedure.

Alternative Name :DNA-directed RNA polymerase II subunit RPB1; RNA polymerase II subunit B1; DNA-directed RNA polymerase II subunit A; DNA-directed RNA polymerase III largest subunit; RNA-directed RNA polymerase II subunit RPB1; POLR2A; POLR2

Immunogen :Synthetic phosphopeptide derived from human Rpb1 around the phosphorylation site of Serine 1619.

Conjugate :Unconjugated

Modification :Phosphorylation
