Fig. 4From: Development of luciferase-linked antibody capture assay based on luciferase immunoprecipitation systems for antibody detection of porcine reproductive and respiratory syndrome virusEvaluation of sequential serum samples obtained from experimentally infected pigs by N-Rluc LACA, nsp1α-Rluc LACA and IDEXX ELISA. Serum samples from 6 pigs experimentally infected with PRRSV-HuN4 strain were collected at indicated time points and evaluated by different methods to compare assay sensitivity between N-Rluc LACA (a) and nsp1α-Rluc LACA (b), with the same serum samples tested in parallel using IDEXX ELISA (c)Back to article page
