title: Ultrastructure of acetylcholine receptor clusters on cultured muscle fibers.
abstract: The structure of regions with a high concentration of ACh receptors (clusters) on cultured skeletal muscle myotubes was examined by immunoperoxidase staining of bound alphaBT. The clusters did not appear to differ from the other regions except in their higher concentration of receptor.
