Detection And Quantification

The aim of the present study was the implementation of molecular techniques in the detection and quantification of allergic substances of peanut in various kinds of food products, e.g., breakfast cereals, chocolates and biscuits that are frequently related to allergies. In some cases, the presence of peanuts can be due to contamination during production and are not declared on the label. A total of 152 samples were collected from supermarkets and were analysed by a Real Time PCR method. The results indicated that 125 samples (83,3%) were found positive in peanut traces but the most important finding is that from the 84 samples that had no allergen declaration for peanuts, 48 (57,1%) of them were found positive. In conclusion, Real Time PCR can be a very important tool for the rapid detection and quantification of food allergens.

Abstract The aim of the study was to develop and validate a real-time PCR method, using a TaqMan probe, for quantification of Mycoplasma suis in porcine blood. No PCR signals with closely related non-haemotrophic mycoplasmas were obtained. The detection limit of PCR for plasmid combined with blood DNA was determined to be 103/reaction (5 μL of DNA) (1.2x105 target copies in 1 mL of blood). The linearity of real-time PCR (near 1) indicates its use as a quantitative method. Real-time and quantitative PCR were sensitive and specific for the detection and quantification of M. suis in the blood of animals with acute and chronic form of eperythrozoonosis. Developed quantitative PCR cannot be used to detect carrier animals with a small amount of M. suis in their blood. The validity of real-time PCR used in the studies was confirmed by the low inter- and intra-assay coefficients of variation. This fact confirms the applicability of the assay in other laboratories.

Процессы обнаружения и количественного определения методом ПЦР в реальном времени в крови пациентов зрелых микроРНК, в том числе и miR-21, должны быть стандартизированы и валидированы. Проведенные нами исследования, показывают, что специфичность метода ПЦР для miR-21 в крови здоровых доноров может быть демонстрирована образованием продукта-ампликона размером 67 нуклеотидов, прецизионность в условиях сходимости и воспроизводимости, выраженная в виде коэффициента вариации, составляет менее 2% и 3 % соответственно, а линейность метода подтверждается коэффицентом корреляции r≥0,99. The processes of detection and quantification by real-time PCR in blood of mature microRNAs, including miR-21, should be standardized and validated. Our studies show that the specificity of PCR method for miR-21 in the blood of healthy donors can be demonstrated by the formation of a 67 bp amplicon product, precision under conditions of convergence and reproducibility, expressed using the coefficient of variation, is less than 2% and 3%, respectively, and the linearity of PCR method for miR-21 is confirmed by the correlation coefficient r≥0.99.
