E2F1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level E2F Transcription Factor 1 (E2F1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level E2F Transcription Factor 1 (E2F1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

E2F-1; PBR3; PRB-binding protein E2F-1; RBAP1; RBAP-1; RBBP3; RBBP-3; RBP3; retinoblastoma-associated protein 1; retinoblastoma-binding protein 3; transcription factor E2F1.

Transcription 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. E2F1 binds preferentially RB1 in a cell-cycle dependent manner. It can mediate both cell proliferation and TP53/p53-dependent apoptosis. Blocks adipocyte differentiation by binding to specific promoters repressing CEBPA binding to its target gene promoters (PubMed:20176812) . Positively regulates transcription of RRP1B (PubMed:20040599) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to E2F Transcription Factor 1 (E2F1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to E2F Transcription Factor 1 (E2F1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain E2F Transcription Factor 1 (E2F1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of E2F Transcription Factor 1 (E2F1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
