Co-localization between GAD67 and parvalbumin in two different colors.

<p>The color of both anti-GAD67 and anti-parvalbumin images was inverted. The bright signal in the inverted GAD67 and parvalbumin images was further replaced with green and red colors respectively (<b>a</b>). After being superimposed together, neuron expressing both GAD67 (green) and parvalbumin (red) became yellow (red arrow head)(<b>b</b>). Scale bar: 100 µm.
