dog cardiac ryanodine receptors (RyR)

Physical form

ascites fluid containing PBS and 0.05% sodium azide.


The antibody reacts strongly with RyR-2 (expressed predominantly in the heart muscle, but also found in stomach, endothelial cells and diffuse areas of the brain; also known as the β isoform), and weakly with RyR-1 (expressed predominantly in skeletal muscle and areas of the brain; also known as the α isoform). It reacts with ryanodine receptor in cardiac muscle of canine, rat, finch and pigeon; in visceral smooth muscle of toad; and in rat brain. It reacts with skeletal muscle of fish and the β isoform of frog, but only weakly with skeletal muscle in rabbit and the α isoform of frog. In immunohistochemistry, the antibody stains are consistent with the endoplasmic reticulum localization of the receptor in the hippocampus.
