Eukaryotic cells take up constituents of the extra-cellular environment and regulate the cell-surface level of membrane proteins via a recycling system of membrane vesicles called endosomes. When cells are taking up elements from the cell-surface it is called endocytosis, and when they are delivered to the cell-surface it is called exocytosis. The transferrin receptor (TfR) is often employed as a model protein for st......阅读全文

狭义来讲，提取指制备物与细胞固体成分或其它结合成分的分离，由固相转入液相或从细胞内生理状态转入外界特定溶液环境的过程，即分离前期被提取物从破碎的细胞中释放出来的过程。如果被提取物程固相或与固体结合，提取时由固相转入液相，常称为固液萃取；如果被提取物已经呈液相存在，提取时由一液相转入转入另一互不相溶的
