A Basic Guide to Real Time PCR in Microbial Diagnostics: Definitions, Parameters, and Everything

PCR Polymerase Chain Reaction is a scientific term and technique in molecular biology which able to generate copies of a specific DNA from two short oligodeoxynucleotide sequences also called primers by a polymerase-dependent repetitive thermal reaction. PCR technique brought a revolution in science especially in molecular biology since its first discovery back in as its simplicity and not a time-consuming trait.

Over the past decades, PCR techniques have been modified to make it suitable for the application in each scientific field. PCR nowadays is involved in almost all studies that required DNA fragments manipulation including in food and medical analysis. By taking advantage of this revolutionary technique and if developed and used well, it would become very beneficial for humanity in many aspects.

PCR Polymerase Chain Reaction is a scientific term and technique in molecular biology which able to generate copies of a specific DNA from two short oligodeoxynucleotide sequences also called primers by a polymerase-dependent repetitive thermal reaction. PCR technique brought a revolution in science especially in molecular biology since its first discovery back in as its simplicity and not a time-consuming trait.

Analyses to ensure food safety and quality are more relevant now because of rapid changes in the quantity, diversity and mobility of food. Food-contamination must be determined to maintain health and up-hold laws, as well as for ethical and cultural concerns. Real-time polymerase chain reaction RT-PCR , a rapid and inexpensive quantitative method to detect the presence of targeted DNA-segments in samples, helps in determining both accidental and intentional adulterations of foods by biological contaminants. This review presents recent developments in theory, techniques, and applications of RT-PCR in food analyses, RT-PCR addresses the limitations of traditional food analyses in terms of sensitivity, range of analytes, multiplexing ability, cost, time, and point-of-care applications. A range of targets, including species of plants or animals which are used as food ingredients, food-borne bacteria or viruses, genetically modified organisms, and allergens, even in highly processed foods can be identified by RT-PCR, even at very low concentrations. Microfluidic RT-PCR eliminates the separate sample-processing step to create opportunities for point-of-care analyses. We also cover the challenges related to using RT-PCR for food analyses, such as the need to further improve sample handling.

Procedures for the identification and detection of adulteration of fish and meat products

The addition or exchange of cheaper fish species instead of more expensive fish species is a known form of fraud in the food industry. This can take place accidentally due to the lack of expertise or act as a fraud. The interest in detecting animal species in meat products is based on religious demands halal and kosher as well as on product adulterations. Authentication of fish and meat products is critical in the food industry.

Quantification of pathogens by molecular methods View all 15 Articles. Real time PCR quantitative PCR, qPCR is now a well-established method for the detection, quantification, and typing of different microbial agents in the areas of clinical and veterinary diagnostics and food safety. Although the concept of PCR is relatively simple, there are specific issues in qPCR that developers and users of this technology must bear in mind. These include the use of correct terminology and definitions, understanding of the principle of PCR, difficulties with interpretation and presentation of data, the limitations of qPCR in different areas of microbial diagnostics and parameters important for the description of qPCR performance.

Real-time PCR in food science : current technology and applications

Molecular Regulatory Networks For each tool its corresponding application area is specified, divided into: Cq calculation, normalization, quantification, CNV, and dPCR.

Review ARTICLE

It is the most sensitive method as yet in quantitative analysis of mRNA. Having emission maxima ranging from nm to nm, these dyes are a high performing, low cost alternative for fluorophores commonly used on real-time thermocyclers such as TET, JOE. These tests can be used to screen the donated blood supply and to detect very early infections before antibodies have been developed. Pre-amplification This step is a normal PCR where the adapters are used as primers. While the principle and ingredients are similar, each use requires specific primers or probes to detect different organisms.
