The Human REG1B ELISA Pair Set is for the quantitative determination of Human REG1B.The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Human REG1B coated on a 96-well plate. Standards and samples are added to the wells, and any Human REG1B present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-Human REG1B 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 Human REG1B present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
