摘要：

Fine structural features of the 'type A' protofibrils in the guinea pig tectorial membrane were examined using negative staining and deep-etching techniques. Negative-stained samples of fragmented tectorial membrane were composed of several fine filamentous subunits showing the clear banding pattern of the type A protofibrils. Deep-etched replicas of the EGTA (ethylene glycol bis-N,N,N',N'-tetraacetic acid)-treated samples showed fine surface structure consisting of several linear arrays of filamentous elements on the extracellular fibrils, which is interpreted to be type A protofibrils. © 1990.
