Figure 1. Western Blot Analysis of eNOS and nNOS in rat lacrimal gland.
Rat liver, cultured rat aorta cells, rat lacrimal gland acini, whole rat lacrimal gland and rat brain were homogenized and proteins separated by SDS-PAGE and transferred to nitrocellulose. Blots were probed with antibodies against eNOS (upper blot) and nNOS (lower blot). Blots shown are representative of three independent experiments.
