THE ELONGATION OF MYOFIBRILS FROM THE INDIRECT FLIGHT MUSCLE OF DROSOPHILA
Myofibrils which lengthen by several per cent in the presence of ATP and magnesium ions were prepared by teasing indirect flight muscle of Drosophila in solutions containing ethylenediaminetetraacetate. A study was made of the hydrogen ion, magnesium ion, ATP, and potassium chloride concentrations...
