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.
Chemistry comes into play in the form of chemical probes or as compounds being evaluated as potential leads or drugs. The use of chemical probes to elucidate biology is the basis of chemical genomics. A large series of compounds are individually introduced into cells, with the aim of identifying a cell that then undergoes a specific phenotypic change.
