Figure 3From: Two types of nanoparticle-based bio-barcode amplification assays to detect HIV-1 p24 antigenLinear dynamic p24 detection ranges of three assays: (A) in-house ELISA, (B) BCA-based microplates and (C) BCA-based MMPs. Each data point represents the average of three independent determinations. Statistical analysis of linear regression model between the signal value of each methods and the concentration of HIV-1 p24 are carried out with SPSS 16.0.Back to article page
