Figure 1From: Quantitative anti-PA IgG ELISA; assessment and comparability with the anthrax toxin neutralization assay in goatsPercentage recovery (%Re) plots for known concentrations of the reference anti-PA IgG standard. %Re indicates percentage recovery for known IgG concentrations of the standard that were tested in the ELISA using a 4-parametre logistic curve model. [%Re = 100(BC/NC), where BC and NC represent the back-calculated and nominal (known) concentrations respectively].Back to article page
