Human TAF13 (TATA Box Binding Protein Associated Factor 13) Microsample ELISA Kit

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 Human TAF13. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human TAF13. 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 Human TAF13, 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 Human TAF13 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 0.32-20 ng/mL. Sensitivity: 0.127 ng/mL. Assay Type: Sandwich. Standard: 20 ng/mL. Sample Type: sTissue homogenates, cell lysates and other biological fluids.. Assay duration: 3.5h. Protein Function: The TFIID basal transcription factor complex plays a major role in the initiation of RNA polymerase II (Pol II)-dependent transcription (PubMed:33795473, PubMed:9695952). TFIID recognizes and binds promoters via its subunit TBP, a TATA-box-binding protein, and promotes assembly of the pre-initiation complex (PIC) (PubMed:33795473). The TFIID complex consists of TBP and TBP-associated factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (PubMed:33795473). TAF13, together with TAF11 and TBP, play key roles during promoter binding by the TFIID and TFIIA transcription factor complexes (PubMed:33795473) [The Uniprot Consortium]
