The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesICC/IF: Use at an assay dependent dilution.
IHC-P: 1/50 - 1/100 for 30 min at RT. Staining of formalin-fixed tissues requires boiling tissue sections in 1mM EDTA, pH 8.0, for 10-20 min followed by cooling at RT for 20 min.
IP: Use at 2µg/mg of lysate. Native and denatured.
WB: Use at a concentration of 1 - 2 µg/ml for 2hrs at RT. Predicted molecular weight: 47 kDa.

FunctionTranscription activator that binds DNA cooperatively with dp proteins through the E2 recognition site, 5'-TTTC[CG]CGC-3' found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. E2F-1 binds preferentially RB1 protein, in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent apoptosis.
Sequence similaritiesBelongs to the E2F/DP family.
Post-translational modificationsPhosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. Acetylation stimulates DNA-binding. Enhanced under stress conditions such as DNA damage and inhibited by retinoblastoma protein pRB. Regulated by KAP1/TRIM28 which recruits HDAC1 to E2F1 resulting in deacetylation. Acetylated by P/CAF/KAT2B.
