Fig. 2From: Integrated approach for detection of SARS-CoV-2 and its variant by utilizing LAMP and ARMS-PCRIn-house colorimetric Assay of SARS-CoV-2 genes. Phenol red and Azure II dye combine to give a blue color, while a modest green coloring that results from the RT-LAMP Assay indicates the presence of a virus. Whereas, the cresol red, which was pink before the reaction and became yellow, confirms the existence of the SARS-CoV-2 geneBack to article page
