Invitrogen™ Human POLR2I (aa 3-102) Control Fragment Recombinant Protein

Product Code. 30208340

Brand: Invitrogen™ RP89316

Description

Recombinant Protein

Highest antigen sequence indentity to the following orthologs: Mouse (100%), Rat (100%). This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-60938 (PA5-60938. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

POLR2I is a subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit, in combination with two other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA. POLR2I has two zinc finger motifs with conserved cysteines and the subunit does possess zinc binding activity. Western blots using two different antibodies against two unique regions of this protein target confirm the same apparent molecular weight in our tests. This gene encodes a subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit, in combination with two other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA. The product of this gene has two zinc finger motifs with conserved cysteines and the subunit does possess zinc binding activity.
