Comparative proteomic phenotyping of cell lines and primary cells to assess preservation of cell type-specific functions.

Abstract excerpt

Biological experiments are most often performed with immortalized cell lines because they are readily available and can be expanded without limitation. However, cell lines may differ from the in vivo situation in important aspects. Here we introduce a straightforward methodology to compare cell lines to their cognate primary cells and to derive a comparative functional phenotype. We used SILAC (stable isotope...
