Fig. 3From: Rapid detection of the common avian leukosis virus subgroups by real-time loop-mediated isothermal amplificationSensitivity of the LAMP detections. Turbidity was monitored by the Loopamp real-time turbidimeter at 400 nm. The detection limits for normal exogenous ALV was 2 × 101 copies/μl of positive samplesBack to article page
