Course detail

Laboratory Classes in Molecular Biotechnology

FCH-MCO_MOB_PAcad. year: 2020/2021

The course is focused on practical mastering of method polymerase chain reaction in identification of bacteria of genus Lactobacillus in milk product (probiotic drink). PCR-ready DNA is isolated from the product using magnetic microspheres. PCR mixtures are prepared after estimation of DNA concentration and quality. DNA is amplified in conventional PCR and in real-time PCR. Working out of for protocols in the form of posters is part of the course.

Learning outcomes of the course unit
