Positivity of the PGDM1400, PGT121 and VRC07-523-LS Triplex PK. 33 HIV-1 seronegative serum samples were spiked with specific concentrations of the PGDM1400, PGT121, and VRC07-523-LS. Percent recovery, calculated as (observed concentration ÷ expected concentration) × 100, for PGMD1400, PGT121 and VRC07-523-LS, respectively is shown on y-axis. The blue dashed lines at levels 70 and 130, show preset acceptance criteria for percent recovery [70-130%]. Numbers on top of each box plot show the percentage and counts (number of samples that met the present acceptance criteria/total number of samples) of samples with a percent recovery between 70-130%. 100% of the samples, for all three bnAbs tested here, had acceptable percent recovery.
