TOP2A ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Topoisomerase II (TOP2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Topoisomerase II (TOP2) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

DNA gyrase; DNA topoisomerase (ATP-hydrolyzing) ; DNA topoisomerase 2-alpha; DNA topoisomerase II, 170 kD; DNA topoisomerase II, alpha isozyme; TOP2; TOP2alpha; TOPIIA; topoisomerase (DNA) II alpha 170kDa; TP2A.

Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes. May play a role in regulating the period length of ARNTL/BMAL1 transcriptional oscillation (By similarity) .

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 Topoisomerase II (TOP2) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Topoisomerase II (TOP2) . 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 Topoisomerase II (TOP2), 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 Topoisomerase II (TOP2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
