Fig. 5. Western blot analysis indicates that IP₃Rs are resistant to detergent extraction. Pancreatic acini were homogenized and used to prepare a Triton X-100-soluble supernatant (S) and a Triton X-100-insoluble pellet (P). Proteins contained in the supernatant and pellet fractions were separated by SDS-PAGE and probed with antibodies recognising (A) actin, (B) myosin IIa and (C) IP₃R3.
