The human CD21 ELISA Pair Set is for the quantitative determination of human CD21 . 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 CD21coated on a 96-well plate. Standards and samples are added to the wells, andany CD21 present binds to the immobilized antibody. The wells are washed and ahorseradish peroxidase conjugated rabbit anti-CD21 polyclonal antibody is thenadded, producing an antibody-antigen-antibody "sandwich". The wells are againwashed and TMB substrate solution is loaded, which produces color in proportionto the amount of CD21 present in the sample. To end the enzyme reaction, thestop solution is added and absorbances of the microwell are read at 450 nm.
CR2Standard (antigene): Each vial contains 110 ng of recombinant CD21. 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 4000 pg/mL is recommended. capture antibody type: 0.1 mg/mL of mouse anti-CD21 monoclonal antibody. Dilute to a working concentration of 2.0 µg/mL in CBS before coating. (Catalog: # 10811-MM11)detection antibody type: 0.5 mg/mL rabbit anti-CD21 polyclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 µg/mL in detection antibody dilution buffer before use.Lable: HRP
The minimum detectable dose of human CD21 was determined to be approximately 62.5 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard..
The average concentration of CD21 in 10 normal human serum is 213.65+/-94.17 ng/mL ranging from 90.41 to 414.21 ng/mL.
