Manipulating cells in the culture • Isolating cells • Disrupt extracellular matrix with proteolytic enzymes or EDTA • Fluorescence-activated cell sorter • Growing cells in culture dishes • Primary cell culture • Prepare directly from tissues of an organism • Cell line • Immortalized, can grow indefinitely
Fractionation of Cells • Organelles and macromolecules can be separated by ultracentrifugation • There are 2 types of sedimentations • Velocity sedimentation • Equilibrium sedimentation
Analyzing Protein Structure and Function • Chromatography / HPLC / FPLC • Ion-exchange/hydrophobic chromatography • Gel-filtration chromatography • Affinity chromatography • Gel Electrophoresis • Western Blotting • Mass spectrometry • X-ray crystallography/NMR spectroscopy • Protein-protein interaction • Protein-DNA interaction
Determination of size and subunit of a protein by SDS polyacrylamide-Gel Electrophoresis
