Adipocytes have been known to secrete a number of important proteins called adipokines with roles in energy metabolism, reproduction, cardiovascular function and immunity. In this study we have attempted to identify intensively secretory proteins from 3T3-L1 adipocytes. 3T3-L1 preadipocytes were dif...

모든 텐덤 질량분석 정보는 무엇을 이용하여 확인했는가? | 모든 텐덤 질량분석 정보는 BioWorks 소프트웨어(버전 3.2)와 연동된 SEQUEST 알고리즘을 이용하여 국제 단백질 색인의 쥐단백질 정보(버전 3.24)에서 확인하였다. | |
RNA는 무엇을 이용하여 추출하는가? | RNA는 100 mm 그릇에 있는 단백체를 얻은 동일한 분화된 지방세포로부터 1ml의 Trizol 을 이용하여 추출하였다. RNA는 제조업체의 설명서에 따라 균질화된 세포로부터 준비되었다. | |
이들 혈청 단백질을 제거하기위하여 세포를 PBS로 1회, 4회 및 6회 세척과정을 통하여 세포외 액에 존재하는 단백질들을 확인하였을 때, 4회 이상 세척하였을 경우 대부분의 혈청 단백질이 제거된 이유는? | 분비성 단백질을 포함한 상층액을 수거하기 전 Phosphate Buffer Solution(PBS)로 세척과정을 극도로 세밀하게 진행하였다. 세척과정의 질적인 변화는 1차원 단백질 전기영동 후 Coomassie Blue 염색으로 확인하였다. 배지의 영양성분으로 이용되는 FBS는 Bovine 혈청의 알부민과 혈청 단백질이 많이 존재한다. 이들을 제거해야 원하는 지방 세포로부터 분비되는 단백질들을 동정할 수 있다. 따라서 이들 혈청 단백질을 제거하기 |
