Food Control™ LFA+ is a PCR-kit for fast and reliable detection of foodborne pathogens via conventional PCR in combination with Minerva-Biolabs reliable Lateral Flow Assay (LFA)+ cartrige technology, putting together the easily interpretable LFA stripe and our PCR contamination avoiding LFA+ cartridge system.
Detecting bacterial contamination is a key aspect in food microbiology. Consequently, microbiological quality control programs are intensified throughout food chain production in order to minimize the risk of intoxicating consumers. Reliability, speed and robustness of a test system to detect the presence or absence, or even the degree of contamination with pathogens, becomes increasingly important. Food Control™ LFA is a diagnostic system for easy non-quantitative detection of presence or absence of foodborne pathogens in agricultural or food industry via conventional PCR and Lateral Flow Cartridge LFA+ technology.
Type of Assay
Food Control™ PCR-LFA+ is based on the regular Food Control™ PCR-LFA design, but provides additionally a convenient pre-casted hybridisation cartridge. This system allows the single-use, cross-contamination safe reading of the PCR result for each sample individually.
The LFA+ cartridge provides the lateral flow stripe and the running buffer required to complete the hybridization and staining process. The PCR tube is inserted into the cartridge. By closing the system a needle taps the tube and the buffer reservoir, instantly starting the flow and the hybridization transferring the PCR amplicons onto the stripe. This one step system reduces preparation and handling steps as well as contamination via e.g. PCR carry over. The result is easily visible through the sight funnel of the cartridge.
Recommended Use / Scope
Can be used in research and industry for detection of pathogenic contamination in food or agricultural products. For research use only! Do not use for clinical diagnostic or testing of patient samples.
The kit is available for the detection of the following microorganisms via conventional PCR:
