Sino Biological Human CTLA-4 Matched ELISA Antibody Pair Set
Supplier: Sino Biological SEK1115915
The Human CTLA-4 ELISA Pair Set is for the quantitative determination of Human CTLA-4.The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Human CTLA-4 coated on a 96-well plate. Standards and samples are added to the wells, and any Human CTLA-4 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-Human CTLA-4 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 Human CTLA-4 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
