Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1.0 - 10.0 ?g/ml. In Western blotting it is recommended to use casein or BSA in the blocking solution rather than non-fat-dry milk. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: immunoprecipitation2,3.

The clone H14 was developed against a purified phosphorylated form of RNA polymerase II extracted from a transformed cell line. Pol II has two physiologically important phosphorylation sites: ser-2 and ser-5. Both sites are found in the heptapeptide repeat YSPTSPS at the C-terminal domain. Clone H14 recognizes the phosphoserine 5 (ser-5) of Pol II. Clone H14 is useful for immunofluorescence and Western blotting.

This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).

Antigen Details

Structure
RPB1 contains a C-terminus composed of heptapeptide repeats that are essential for polymerase activity. These repeats contain Ser and Thr residues that are phosphorylated in actively transcribing RNA polymerase. The predicted molecular weight is 220 kD.
Distribution

Nucleus and cytosol.

Function
RPB1 is the largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes.
