Introduction of ferritin inside muscle fibres deprived of the sarcolemma puts in evidence the presence of two lines, here called N lines, which cross the I band. In correspondence of the N(1) line, which is nearer to the Z line, the thin fi...
Localized deposition of lead phosphate precipitate in glycerinated rabbit psoas muscle during ATP-induced contraction [0.03%]
