is about has specified input has specified output cell core promoter sequence-specific DNA binding assay promoter activity detection by reporter gene assay IEDB promoter activity detection by reporter gene assay A T cell hybridoma in which the beta-galactosidase gene (lacZ) was inserted under the control of the IL-2 promoter, is detected by adding the X-gal substrate which when cleaved by lacZ results in detectable blue color. An assay in which the activity of a promoter in a cell is monitored by using a reporter gene that was inserted in a genomic location under control of the promoter and whose expression can be easily detected based on qualities or functions of the gene.
