中英文说明书丨MyBioSource 犬尿氨酸 ELISA试剂盒

MBS495082 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Kynurenine, ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing Kynurenine. The ELISA analytical biochemical technique of the MBS495082 kit is based on Kynurenine antibody-Kynurenine antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect Kynurenine antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, Kynurenine. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Intended Uses:

Enzyme Immunoassay for the quantitative determination of L-Kynurenine in serum, plasma and various biological samples. After acylation Kynurenine is quantitatively determined by ELISA. The competitive ELISA uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The acylated standards, controls and samples and the solid phase bound analyte compete for a fixed number of antibody binding sites. When the system is in equilibrium, free antigen and free antigen-antibody complexes are removed by washing. The antibody bound to the solid phase is detected by an anti-rabbit IgG-peroxidase conjugate using TMB as a substrate. The reaction Is monitored at 450 nm. Quantification of unknown samples is achieved by comparing their absorbance with a reference curve prepared with known standards.
