Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to N-glycosylase/DNA lyase. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for N-glycosylase/DNA lyase and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain N-glycosylase/DNA lyase, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The concentration of N-glycosylase/DNA lyase in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Uniprot Description
OGG1: DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N- methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta- lyase activity that nicks DNA 3' to the lesion. Defects in OGG1 may be a cause of renal cell carcinoma (RCC). It is a heterogeneous group of sporadic or hereditary carcinoma derived from cells of the proximal renal tubular epithelium. It is subclassified into clear cell renal carcinoma (non-papillary carcinoma), papillary renal cell carcinoma, chromophobe renal cell carcinoma, collecting duct carcinoma with medullary carcinoma of the kidney, and unclassified renal cell carcinoma. Belongs to the type-1 OGG1 family. 8 isoforms of the human protein are produced by alternative splicing.
