β¦ Synopsis
Sections through the soleus muscle of the rat were incubated with concanavalin A (Con A) or wheat germ agglutinin (WGA) conjugated to fluorescein isothiocyanate. Binding of these lectins to structures which comprise the muscle spindle was studied by fluorescence microscopy. The distribution of the lectins was heaviest in the outer capsule of the spindle and at the surface of intrafusal muscle fibres. The periaxial space in the equatorial region of spindles was unlabelled except in the immediate vicinity of the axial bundle. Binding by Con A was more extensive than by WGA, suggesting that more glucopyranoside units are accessible within the muscle spindle than are those of N-acetylglucosamine.
