E. coli 16S-Biotin Probe
E. coli 16S CENPB PNA FISH PROBES
The E. coli 16S-Biotin-Ahx Probe is a sequence-specific PNA probe developed for the selective detection of Escherichia coli, including O157:H7 strains. The probe sequence targets a defined region within the bacterial 16S rRNA, enabling accurate identification. It is designed for use in PNA-FISH, a rapid technique that detects microorganisms directly by hybridizing to intracellular rRNA.
Main characteristics
This PNA probe enables sequence-specific detection of E. coli O157:H7 and is designed for use in PNA-FISH applications targeting rRNA. It provides high specificity for regions associated with enterohemorrhagic E. coli (EHEC) and benefits from the neutral PNA backbone, which ensures strong and stable hybridization. The method allows rapid and sensitive detection without the need for PCR amplification, making it well suited for microbial identification workflows. The probe is conjugated with biotin, enabling detection through streptavidin-based systems for flexible signal development. A terminal glycine can be incorporated to increase flexibility and support optimal binding without affecting specificity.
Applications
- Identification of E. coli O157:H7 in clinical microbiology samples
- Screening for pathogenic E. coli in food safety testing
- Monitoring of environmental samples such as water and agricultural sources
- Use in PNA-FISH methods for microbial detection
- Research on enterohemorrhagic E. coli and similar pathogens
