TTF1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Transcription Termination Factor, RNA polymerase I (TTF1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Transcription Termination Factor, RNA polymerase I (TTF1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

RNA polymerase I termination factor; transcription termination factor 1; Transcription termination factor I; transcription termination factor, RNA polymerase I; TTF-1; TTF-I.

Multifunctional nucleolar protein that terminates ribosomal gene transcription, mediates replication fork arrest and regulates RNA polymerase I transcription on chromatin. Plays a dual role in rDNA regulation, being involved in both activation and silencing of rDNA transcription. Interaction with BAZ2A/TIP5 recovers DNA-binding activity.

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 Transcription Termination Factor, RNA polymerase I (TTF1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Transcription Termination Factor, RNA polymerase I (TTF1) . 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 Transcription Termination Factor, RNA polymerase I (TTF1), 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 Transcription Termination Factor, RNA polymerase I (TTF1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
