From: Two types of nanoparticle-based bio-barcode amplification assays to detect HIV-1 p24 antigen
Relative HIV-1 p24 antigen detection sensitivity using 2 BCA-based assays and an in-house ELISA assay. The X axis represents serial dilutions (log10) of HIV-1 p24 antigen, the left Y axis is OD 450 value for ELISA, and the right Y axis is the DNA amounts (pmoles) calculated from gel electrophoresis band of samples for the two BCA assays. Each data point represents the average of 3 independent determinations. Squares : ELISA, circles: microplate method, and triangles: MMPs method.
