Figure 3 The mean grey level of the spot against various amount of H. IgG immobilized on the protein array. The concentrations of human IgG spotted from lane 1 to lane 6 are as follows: 1.25, 2.5, 5, 10, 20, 40 μg/mL. The optimized amount of SPA binding to colloid gold was 12 μg/mL. The data in the plot were obtained from the image of CCD by averaging the mean grey levels of the 6 replicate spots.
