The Human Cystatin SA / CST2 ELISA Pair Set is for the quantitative determination of Human Cystatin SA / CST2. 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 SA / CST2 coated on a 96-well plate. Standards and samples are added to the wells, and any Cystatin SA / CST2 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-Cystatin SA / CST2 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 SA / CST2 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
CST2Standard (antigene): Each vial contains 15 ng of recombinant CST2. 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 using 2-fold serial dilutions in sample dilution buffer, and a high standard of 0.3 ng/mL is recommended. capture antibody type: 1.0 mg/mL of rabbit anti-CST2 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 µg/mL in CBS before coating. (Catalog: # 11567-R005)detection antibody type: 0.25 mg/mL rabbit anti-CST2 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % glycerol, pH 7.4). Dilute to working concentration of 0.5 µg/mL in detection antibody dilution buffer before use. (Catalog: # 11567-R016)Lable: HRP
The minimum detectable dose of Human Cystatin SA / CST2 was determined to be approximately 4.7 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
