Function of western blot
WebDifferent detection methods are used to visualize the nucleic acids and specific proteins transferred to membrane support. Southern and northern blotting involves the use of radioactive probes, and the detection involves exposure to X-ray or autoradiography film in the dark. In Western blotting, the proteins on the nitrocellulose membrane may ... WebThe membrane supports, such as nitrocellulose and polyvinylidene diflurode (PVDF), used in western blotting have a high affinity for proteins. To prevent non-specific binding of detection antibodies during the steps following transfer, unoccupied sites on the membrane surface must be blocked.
