Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.

NP_072114

This assay has high sensitivity and excellent specificity for detection of Transketolase (TKT).No significant cross-reactivity or interference between Transketolase (TKT) and analogues was observed.

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

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Transketolase (TKT) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Transketolase (TKT) were tested on 3 different plates, 8 replicates in each plate.
