1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Recruits TFIIH to the initiation complex and stimulates the RNA polymerase II C-terminal domain kinase and DNA-dependent ATPase activities of TFIIH. Both TFIIH and TFIIE are required for promoter clearance by RNA polymerase.
Belongs to the TFIIE alpha subunit family. Contains 1 HTH TFE/IIEalpha-type domain.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human colon carcinoma (left) and mouse renal cell carcinoma (right) tissues labelling TFIIE alpha with ab99418 at 1/200 (1µg/ml). Detection: DAB.
Western blot - TFIIE alpha antibody (ab99418)
All lanes : Anti-TFIIE alpha antibody (ab99418) at 0.04 µg/ml
Lane 1 : HeLa whole cell lysate at 50 µg Lane 2 : HeLa whole cell lysate at 15 µg Lane 3 : HeLa whole cell lysate at 5 µg Lane 4 : 293T whole cell lysate at 50 µg Lane 5 : Mouse NIH3T3 whole cell lysate at 50 µg
ab99418 at 0.4 µg/ml detecting TFIIE alpha in HeLa whole cell lysate by western blot analysis following immunoprecipitation. Detection utilised ECL with a 3 second exposure.
For immunoprecipitation, ab99418 was used at at 3 µg/mg lysate; 1 mg of lysate was used for IP and 20% of IP was loaded.
Lane 1; IP using ab99416, a rabbit anti-TFIIE alpha antibody which recognizes an upstream epitope
Lane 2; IP using ab99418.
Lane 3; IP using control IgG.
