Scale box in millimeters. Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside.
vesicles from adrenal cortex contained clathrin as the major protein component. In contrast to the coated vesicles of adrenal cortex, however, the brain coated vesicles failed to reveal masked LDL receptor activity when treated with octylglucoside. The current data indicate that isolated coated ves- icles from the adrenal cortex contain LDL receptors and that these receptors exist in a masked form,
