ELISA Transcription factor E2F2 (E2F2)

Reactivity: (Homo sapiens) UniProt:Q14209 Abbreviation:E2F2 Alternative Names:E2F-2; Application:ELISA Range:0.156-10 ng/mL Sensitivity:0.058 ng/mL Intra-AssayCV:?5.2% Inter-AssayCV:?8.3% Recovery:0.88 Sample Type:Serum, Plasma, Other biological fluids Detection Method:Sandwich Analysis Method??:Quantitive Test principle:This assay employs a two-site sandwich ELISA to quantitate E2F2 in samples. An antibody specific for E2F2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyE2F2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for E2F2 is added to the wells. After washing, Streptavidin conjµgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of E2F2 bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:E2F2 is a member of the E2F family of transcription factors. The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. These domains include a DNA binding domain, a dimerization domain which determines interaction with the differentiation regµLated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F1 and E2F3, have an additional cyclin binding domain. This protein binds specifically to retinoblastoma protein pRB in a cell-cycle dependent manner, and it exhibits overall 46% amino acid identity to E2F1. Stability:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calcµLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
