Capture antibody detection antibody
WebThe sandwich ELISA quantify antigens between two layers of antibodies (i.e. capture and detection antibody). The antigen to be measured must contain at least two antigenic epitope capable of binding to antibody, since at least two antibodies act in the sandwich. Either monoclonal or polyclonal antibodies can be used as the capture and detection ... WebWhat you need to do is try 3-5 concentrations with your capture antibody and perform the ELISA with the standard alone and maybe 1-2 concentrations with your detection antibody (0.5 and 1 ug/ml, ex).
