Overview
| Product Name: | Human Cys-C (Cystatin C) ELISA Kit |
| Catalog No: | CUBEK02054 |
| Description: | This ELISA kit applies to the in vitro quantitative determination of Human Cys-C concentrations in serum, plasma and other biological fluids. |
| Quantity: | 12 X 8-well Strips (96T) |
| Target Species: | Human |
| Tested Applications: | ELISA |
| Specificity: | This kit recognizes natural and recombinant human Cys-C. No significant cross-reactivity or interference between human Cys-C and analogues was observed. |
| Pinciple: | The Human Cys-C (Cystatin C) ELISA Kit uses the Sandwich-ELISA method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to human Cys-C. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. A biotinylated detection antibody specific for human Cys-C and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each well, successively, and the plate is incubated at 37˚C. The wells are washed and the substrate solution is added. Wells containing human Cys-C, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme substrate is terminated by the addition of a sulfuric acid solution, turning the solution yellow. The optical density (OD) is measured spectrophotometrically at wavelength of 450 nm. The OD value is proportional to the concentration of the human Cys-C. You can calculate the concentration of human Cys-C in the samples by comparing the OD of the samples to the standard curve. |
