The Complement 1q (C1q) BioAssay ELISA Kit (Mouse) is a sandwich enzyme immunoassay for the in vitro quantitative measurement of C1q in mouse serum,plasma and other biological fluids.Detection Range:0.625 - 40ng/mlSensitivity:<0.241ng/mlPrecision:Intra-Assay: CV<10%Inter-Assay: CV<12%Test Principle:The microtiter plate provided in this kit has been pre-coated with an antibody specific to C1q. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to C1q. 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 C1q,biotin-conjugated antibody and enzyme-conjugated Avidin 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 C1q in the sample is then determined by comparing the O.D. of the sample to the standard curve.Kit Components:*365874A: Microtiter Plate,1x96 wells.

Store all the other components at 4°C. Unused kit is stable for 6 months. Once kit components are opened,it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product,centrifuge the original vials after thawing and prior to removing the cap.Assay Procedure Summary:1. Prepare all reagents,samples and standards.2.
