RTPCR of angiotensin receptor expression.

Graph plots the relative expression of five tissues tested for the presence of AT1a, AT1b, and AT2 receptors- kidney, adrenal gland, retina, sclera and optic nerve from a CD1 mouse. To help normalize the results, a value was calculated by dividing the GAPDH primer treated tissue value by the mean quantification cycle (Cq) value for AT1A, AT1B, or AT2 primer tissue (relative expression). A lower value than 1 indicates a lower value for that receptor in tissue compared to GAPDH.
