Neurosecretory granules (NSG) containing hindgut-stimulating neurohormone (HSN) from Leucophaea maderae were isolated by densitygradient centrifugation of cockroach brain homogenates. High concentrations of HSN were consistently found in isolates containing large numbers of NSG. HSN was measured by...
