Fig. 1From: Detection of low-load Epstein-Barr virus in blood samples by enriched recombinase aided amplification assayBubble chart based on the viral load detected by the traditional qPCR and the qPCR assay followed by M1 bead enrichment. The bubble size is the square root of viral load, the number of blue bubbles is the number of positive samples after enrichment, the number of pink bubbles is the number of positive samples before enrichment. The common center of two bubbles shared by the same sampleBack to article page
