Once a cell type is chose (we will work with liver), it is important to obtain the organelles in ... The particular fractionation procedure we will use was designed to maximize the activity of mitochondria (they are extremely fragile) while partially sacrificing the yield and resolution of some of the more stable fractions.

A host of fractionation procedures are employed by cell biologists. Each organelle has characteristics (size, shape and density for example) which make it different from other organelles within the same cell. If the cell is broken open in a gentle manner, ... Ultrasonification is a useful adjunct to this procedure,

Red cell isolation ... Any fractionation procedure results in losses due to incomplete separation of components, materials sticking to surfaces, and fluids left behind after transfer. The smaller the final pellet, the more likely too much of it will be lost through attrition.

Since the procedure sediments large organelles first, they are often contaminated by the smaller organelles which start at the bottom of the centrifuge tube. ... For more information on cell fractionation, look at pages 162-165 in your textbook (especially figure 4-35).

An important requirement for successful cell fractionation is the evaluation of the isolation procedure, usually accomplished using morphological and/or biochemical methods. The morphological approach applies light and electron microscopy of thin section to the various fractions obtained.
