Antibody was affinity purified using an epitope specific to Paf1 immobilized on solid support. The epitope recognized by A300-173A maps to a region between residues 475 and 525 of human RNA Polymerase Associated Factor using the numbering given in TrEMBL entry Q9NUU9 (GeneID 54623). Immunoglobulin concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.

Detection of human Paf1 by western blot of immunoprecipitates. Samples: Whole cell lysate (0.5 or 1.0 mg per IP reaction; 20% of IP loaded) from HeLa cells prepared using NETN lysis buffer. Antibodies: Affinity purified rabbit anti-Paf1 antibody A300-173A (lot A300-173A-3) used for IP at 6 µg per reaction. Paf1 was also immunoprecipitated by a previous lot of this antibody (lot A300-173A-2) and rabbit anti-Paf1 antibody A300-172A-2 For blotting immunoprecipitated Paf1, A300-173A was used at 0.1 µg/ml. Detection: Chemiluminescence with an exposure time of 3 minutes.
