Lk. Poulsen et al., SIMULTANEOUS DETERMINATION OF GENE-EXPRESSION AND BACTERIAL IDENTITY IN SINGLE CELLS IN DEFINED MIXTURES OF PURE CULTURES, Applied and environmental microbiology, 63(9), 1997, pp. 3698-3702
A protocol was developed to achieve the simultaneous determination of
gene expression and bacterial identity at the level of single cells: a
chromogenic beta-galactosidase activity assay was combined with in si
tu hybridization of Fluorescently labelled oligonucleotide probes to r
RNA. The method allows monitoring of gene expression and quantificatio
n of beta-galactosidase activity in single cells.
