Protein extraction involves isolating proteins from complex biological samples while maintaining their functionality. It often requires a careful choice of extraction buffers that contain salts, detergents, or stabilizers to preserve protein structure and activity. The solubilization step is crucial for proteins that are membrane-bound or insoluble in aqueous solutions. Detergents such as Triton X-100 or SDS can be used to solubilize proteins from membranes by disrupting lipid bilayers, allowing for effective extraction.
