Neuronally mediated enzyme induction in adrenergic neurons and adrenal chromaffin cells.

_I BHARMACIA GRADIENT MIXER GM-1 The prime requirement for the production of linear ionic strength gradients is efficient mixing of the components of the gradient. In the Pharmacia Gradient Mixer GM-1 this is achieved by a blade configuration which lifts the dense incoming solution from the bottom of the mixing chamber and distributes i t evenly throughout the whole eluant at a low stirring speed. Gradients in aqueous and most organic solvents can be formed with the GM-I.
