Tapping mode atomic force microscopy is demonstrated for topographic investigation of isolated ryanodine receptors of rabbit skeletal muscle (RyR1) both in air and in a buffer. In air, the micrographs appeared to have four-fold symmetry and showed two different configurations depending on the presence or absence of a center protrusion. Despite the squareness of the images discerned of RyR1s in the buffer, the detailed topography of RyR1 appeared different from that in air. Possible reasons for this are discussed.
