The Human Cystatin S / CST4 ELISA Pair Set is for the quantitative determination of Human Cystatin S / CST4. This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs. The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Cystatin S / CST4 coated on a 96-well plate. Standards and samples are added to the wells, and any Cystatin S / CST4 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated mouse anti-Cystatin S / CST4 monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of Cystatin S / CST4 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
CST4Standard (antigene): Each vial contains 37 ng of recombinant CST4. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20°C; to -80°C; in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 150 pg/mL is recommended. capture antibody type: 0.5 mg/mL of mouse anti-CST4 monoclonal antibody, Dilute to a working concentration of 2 µg/mL in CBS before coating. (Catalog: # 11542-MM01)detection antibody type: 0.5 mg/mL mouse anti-CST4 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 µg/mL in detection antibody dilution buffer before use. (Catalog: # 11542-MM10)Lable: HRP
The minimum detectable dose of Human Cystatin S / CST4 was determined to be approximately 2.4 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
