Mouse Nei Endonuclease VIII Like Protein 3 (NEIL3) ELISA Kit

Principle of the Assay

The microtiter plate provided in this kit has been pre-coated with an antibody specific to NEIL3. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to NEIL3. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain NEIL3, 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 NEIL3 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Target Information

DNA glycosylase which prefers single-stranded DNA (ssDNA), or partially ssDNA structures such as bubble and fork structures, to double-stranded DNA (dsDNA) (PubMed:20185759, PubMed:22065741, PubMed:22569481, PubMed:22959434, PubMed:23305905, PubMed:23313161). Mediates interstrand cross-link repair in response to replication stress: acts by mediating DNA glycosylase activity, cleaving one of the two N-glycosyl bonds comprising the interstrand cross-link, which avoids the formation of a double-strand break but generates an abasic site that is bypassed by translesion synthesis polymerases (By similarity). In vitro, displays strong glycosylase activity towards the hydantoin lesions spiroiminodihydantoin (Sp) and guanidinohydantoin (Gh) in both ssDNA and dsDNA; also recognizes FapyA, FapyG, 5-OHU, 5-OHC, 5-OHMH, Tg and 8-oxoA lesions in ssDNA (PubMed:20185759, PubMed:22065741, PubMed:22569481, PubMed:22959434, PubMed:23305905, PubMed:23313161). No activity on 8-oxoG detected (PubMed:20185759, PubMed:22065741, PubMed:22569481, PubMed:22959434, PubMed:23305905, PubMed:23313161). Also shows weak DNA-(apurinic or apyrimidinic site) lyase activity (PubMed:20185759, PubMed:22065741, PubMed:22569481, PubMed:22959434, PubMed:23305905, PubMed:23313161). In vivo, appears to be the primary enzyme involved in removing Sp and Gh from ssDNA in neonatal tissues (PubMed:20185759, PubMed:22065741, PubMed:22569481, PubMed:22959434, PubMed:23305905, PubMed:23313161).

Performance Characteristics

REPEATABILITY	Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level NEIL3 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level NEIL3 were tested on 3 different plates, with 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%
SENSITIVITY	The minimum detectable dose was 0.061ng/mL.
ASSAY RANGE	0.156-10ng/mL
SPECIFICITY	This assay has high sensitivity and excellent specificity for the detection of NEIL3. No significant cross-reactivity or interference between NEIL3 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between NEIL3 and all analogs, therefore, cross reactivity may still exist.
