Human CD55 / DAF ELISA Pair Set

Brand

Sino Biological

short description

The human CD55 ELISA Pair Set is for the quantitative determination of human CD55. 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 CD55coated on a 96-well plate. Standards and samples are added to the wells, andany CD55 present binds to the immobilized antibody. The wells are washed and ahorseradish peroxidase conjugated mouse anti-CD55 monoclonal 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 CD55 present in the sample. To end the enzyme reaction, thestop solution is added and absorbances of the microwell are read at 450 nm.

detection target

CD55
Standard (antigene): Each vial contains 30 ng of recombinant CD55. 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 1.5 ng/mL is recommended
capture antibody type: 1.0 mg/mL of rabbit anti-CD55 monoclonal antibody. Dilute to a working concentration of 2 µg/mL in CBS before coating. (Catalog: # 10101-R028)
detection antibody type: 0.4 mg/mL mouse anti-CD55 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.2 µg/mL in detection antibody dilution buffer before use. (Catalog: # 10101-MM03)
Lable: HRP

sensitivity

The minimum detectable dose of human CD55 was determined to be approximately 23.44 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.

Detection limitation

23.44 pg/ml

The average concentration of CD55 in 20 normal human serum is 51.23+/-7.64 ng/mL ranging from 38.9 to 67.3 ng/mL.
