BIOINFORMATICS — INSTRUMENT INTERPRETATION PROTEOMIC PROFILES OF MEAT PROTEIN

Proteomic technologies have proven very effective for detection in meat products of biochemical changes, such as changes in heat resistant and species-specific proteins that could be relevant bio-markers. In the work presented in this report (for the period of 2013–2016), several tissue-specific proteins were detected in the samples of meat and specially developed meat products using proteomic technologies and identified as individual biomarkers in meat product control. The existence of a large number of different proteins resulted in the need to create information arrays — databases (or banks). Currently, there are a number of general and specialized databases that are available online to anyone interested. When studying protein proteomic profiles, many scientists stop at the stage of two-dimensional electrophoregrams sometimes even without ideas about the future prospects of using modern instruments and bioinformation resources to confirm or refute their hypotheses, and sometimes just to identify. This overview shows the chain of actions that allows going from profiling proteins in the gel to a specific interpretation of the results. Studies in this field have enabled formulating and significantly expanding the approaches to the identification and quantification of protein markers of quality, functionality and safety of meat raw material (detection of falsification) in the finished meat products. Based on the obtained data, the information was systematized using bioinformatics techniques with creation of the unique Atlas «Proteomic profiles of farm animal meat proteins.»
