Fig. 4From: A loop-mediated isothermal amplification assay for the detection and quantification of JC polyomavirus in cerebrospinal fluid: a diagnostic and clinical management tool and technique for progressive multifocal leukoencephalopathyRelationship between the LAMP results and the JCV genome copy numbers of samples. The assay was performed twice independently using 2 μL of extracted DNA with the qPCR-positive (n = 50). Circles show the JCV genome copy number of the sample per reaction determined by the qPCR. The vertical lines and values indicate the median values of the JCV genome copy number of the samples per reaction for each result group. The dashed line indicates the 100% detection limit of log101.3 (=20) copies/reactionBack to article page
