The Deoxyribonuclease Gamma (DNASE1L3) BioAssay™ ELISA Kit is a quantitative sandwich assay for the detection of DNASE1L3 in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
Detection Range:0.156-10ng/ml
Sensitivity:0.094ng/ml
Precision:Intra-Assay: CV<8%Inter-Assay: CV<10%
Assay Principle:The microtiter plate provided in this kit has been pre-coated with an antibody specific to DNASE1L3. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to DNASE1L3. Streptavidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain DNASE1L3, Biotin-conjugated antibody and enzyme-conjugated Streptavidin complex will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of DNASE1L3 in the sample is then determined by comparing the O.D. of the sample to the standard curve.
Storage and Stability:Store unopened *519214A at 4ºC; store at -20ºC once opened. Store unopened *519214B at 4°C; once reconstituted, store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
