Production of the gold labeled monoclonal antibody against MC-LR. Study the simple mechanism of the conjugation by the spectral analysis. Production and purification monoclonal antibodies against MC-LR by hybridoma technology. Production the 20nm colloidal gold and label the monoclonal antibody. Study the gold--McAb conjugate by the spectroanalysis. Monoclonal antibody produced by the hybridoma cells were tested for subtypes and designated as IgG2a for 8C11. The titers of antibody in ascites was 108.The IC50 for MC-LR was around 3ng/ml. The IgG molecule weight was 1.5 x 10(5). The structure of the antibody was altered to more tighter and stabler. Product the gold labeled monoclonalantibody against MC-LR conjugate successfully and keep the antige-binding determinant.
