Abstract:
본 발명은 프로테오믹스와 메타볼로믹스 기술을 융합하여 시도된 육질 판별용 마커인 creatine(크레아틴)을 이용하여 돼지의 육질을 판정할 수 있는 우수한 육질을 가진 돼지를 선별할 수 있는 바이오 마커 및 상기 마커를 이용한 돼지의 육질판정방법에 관한 것으로 160여 개의 기존 등록된 대사체 프로파일을 high pH군과 low pH군의 혈청과 근육에서 비교 발굴하여 바이오 마커를 선별하였다.
Abstract:
PURPOSE: A method for determining pork meat quality using a biomarker which is able to select pork of high quality is provided to reduce production cost by selecting and raising pork of high quality and to save time and cost for quality test. CONSTITUTION: A biomarker which is able to select pork having high quality is creatine and creatine kinase. A method for developing the biomarker comprises: a step of extracting total protein from pork loin; a step of dissolving and extracting protein powder and centrifuging; a step of collecting supernatant and performing electrophoresis; a step of dyeing with silver and comparing protein expression; a step of isolating protein spot from the two-dimensional gel and performing hydrolysis; a step of analyzing proteome profiling from pork muscle between high pH and low pH groups; a step of analyzing serum sample of the high pH and low pH groups with 1H-NMR; and a step of confirming that the metabolite compositions are different between the groups.
