Web1.1.1.1 Immunofluorescence Assay. IFA is a microscopic method that can detect and visualize the viral proteins expressed in cells via antigen—antibody reaction ( Fig. 4.2 ). First of all, the virus infected cells are grown on cover glass. To visualize the antigen, the cells are then fixed by paraformaldehyde so that the proteins in the cells ... WebMay 11, 2024 · the TaqMan assay only measures amplification progression of the target sequence, as the probes are target specific. you can monitor the quantity of various qPCR products in a single reaction by adding different primers and TaqMan probes with different reporter dyes to the master mix.
