Density-gradient centrifugation isolation of hormone-containing neurosecretory granules from the cockroach, Leucophaea maderae

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...

Summary: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 bioassay and the NSG were identified by electron microscopy.
