  • Notes

    The human CD48 test is based on the quantitative sandwich enzyme immunoassay technique. Microplate wells are pre-coated with anti-human CD48-specific polyclonal capture antibodies. Samples and standards are pipetted into microwells and human CD48 molecules present in the sample are bound by the capture antibodies. After incubation, unbound material is removed by washing the wells. Then, horseradish peroxidase (HRP) conjugated human CD48-specific polyclonal detection antibodies bind to different epitopes of human CD48 molecules. After washing, the ready to use HRP substrate (TMB) is added to wells. The intensity of the color produced is directly proportional to the amount of human CD48 in the sample. Color development is then stopped by the addition of stop solution. Absorbance is measured at 450 nm.
