The human CD200 ELISA Pair Set is for the quantitative determinationof human CD200. 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 CD200 coated on a 96-well plate. Standards and samples are added to the wells, and any CD200 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-CD200 polyclonal 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 CD200 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
CD200Standard (antigene): Each vial contains 190 ng of recombinant CD200. 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 2 ng/mL is recommended. capture antibody type: 0.5 mg/mL of Rabbit anti-CD200 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 1 µg/mL in PBS before coating. (Catalog: # 10886-R005)detection antibody type: 0.2 mg/mL rabbit anti-CD200 polyclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-protector, pH 7.4). Dilute to a working concentration of 0.5 µg/mL in detection antibody dilution buffer before use.Lable: HRP
The minimum detectable dose of human CD200 was determined to be approximately 31.25 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
