Freeze-fracture replication is the technique that allows investigation of the microheterogeneity of a membrane so that one can see localized differences in protein distribution within membranes. This technique involves freezing and fracturing the sample, then replicating the fracture surface with a heavy metal such as platinum to create a replica of the membrane surface that can be observed under a microscope.
