The AuNP adsorption assay results of human IgG solution spiked with different prostate tissue lysates. All samples were prepared by spiking 1 μL tissue lysate into 20 μL IgG solution. The concentration of IgG solution was 1 mg/mL in phosphate buffer (10 mM, pH 7.4). The prepared samples were incubated at r.t. for 30 min before assay was conducted. Particle size was measured after 3 minutes of human IgG-AuNP incubation. The 'normal range' threshold (red dotted line) was set as 2SD below the mean of the normal control group analyses.
