Since several synaptic proteins aggregate after boiling, these lysates are unboiled. Boil sample before loading, if this is recommended for your protocol.
In many cases the relative concentration of the protein of interest is high enough to use whole tissue lysate for Western blot testing. If the concentration is less than 0.2% of total protein it may be difficult to distinguish signals from background noise. Since a lot of proteins are localized in distinct cellular compartments, subfractioning may overcome this problem. Protein concentration has been determined with a Bradford protein quantification assay.
