Sandwich assay for mixed-sequence recognition of double-stranded DNA: Invader-based detection of targets specific to foodborne pathogens†
Abstract
A 96-well plate sandwich assay based on Invader capture/signalling probes is used to recognize 28-mer mixed-sequence dsDNA targets specific to Salmonella enterica, Campylobacter jejuni, Escherichia coli. Targets are detected down to 20–55 pM concentration with excellent binding specificity.
