Subcellular Fractionation & Protein Distribution

Proteins within a cell are often localised to specific cellular compartments, such as the nucleus, mitochondria, plasma membrane, or vesicles and their specific localisation can provide crucial information about the function of the protein.  An important technique in identifying novel proteins and understanding their function is subcellular fractionation.  This process allows cells to be fractionated into compartment enriched fractions, often utilising differential centrifugation.  In addition to separating compartment specific fractions, subcellular fractionation drastically reduces the complexity of protein samples allowing for easier identification.
 
The Subcellular Fractionation kit exposes students to how research laboratories handle delicate samples for protein analysis and it serves as an advanced training in protein electrophoresis and protein analysis. This study involves the subcellular fractionation of a tissue sample into fractions enriched with nuclear, mitochondria or cytoplasm proteins.  Students also learn about centrifugation techniques and differential centrifugation of samples for fractionation of cellular subcompartments.  Students then use electrophoresis to analyse the fractionated cellular compartments and study how protein distribution or protein fingerprints differ between the subcellular compartments. Finally, students will develop an understanding of cell organelles and cellular organisation.
 
Supplied with components needed for hands-on experimentation for six workstations of 4-5 students or 24-30 students. Supplied with Teacher’s Guide and separate Student’s Guides.
