Gene Information

General description

The antibody reacts strongly with RyR-1 (expressed predominantly in skeletal muscle and areas of the brain; also known as the α isoform) and 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). In immunohistochemistry, the antibody stains are consistent with the endoplasmic reticulum localization of the receptor in rat hippocampus.
The ryanodine receptor (RyR) is the channel responsible for the release of Ca2+ from the sarcoplasmic reticulum (SR) in muscle cells and it also plays a role in Ca2+ regulation in non-muscle cells. The RyR exists as a homotetramer and is predicted to have a short cytoplasmic C-terminus and 4-10 transmembrane domains; the remainder of the protein, termed the "foot" region is located in the cytoplasm between the T-tubule and the SR. The mammalian RyR is the product of three different genes: RyR-1, which is expressed predominantly in skeletal muscle and areas of the brain, RyR-2, which is expressed predominantly in the heart muscle but also found in the stomach, endothelial cells and diffuse areas of the brain, and RyR-3 which is found in smooth muscle and the brain (striatum, thalamus and hippocampus).

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Mouse monoclonal clone 34C anti-Ryanodine receptor is used to tag ryanodine receptors for detection and quantitation by immunocytochemical and immunohistochemical (IHC) techniques. It is used as a probe to determine the presence and roles of ryanodine receptor in studies of calcium flux from the sarcoplasmic reticulum of muscle cells.

Physical form

Purified IgG1 antibody containing 0.05% sodium azide.

Mitochondrial calcium handling and its relation with calcium released from sarcoplasmic reticulum (SR) in muscle tissue are subject of lively debate. In this study we aimed to clarify how the SR determines mitochondrial calcium handling using dCASQ-null mice which lack

This study investigated the release of prostaglandin E2 (PGE2) from cartilage following an impact load in vitro and the possible chondroprotective effect of cyclooxygenase-2 (COX-2) inhibition using non-steroidal anti-inflammatory drugs (NSAIDs). Explants of human articular cartilage were subjected to a

Previous research indicated that nitric oxide synthase (NOS) is the key molecule for S-nitrosylation of ryanodine receptor 1 (RyR1) in DMD model mice (mdx mice) and that both neuronal NOS (nNOS) and inducible NOS (iNOS) might contribute to the reaction

The sarcoplasmic reticulum (SR) is a specialized form of endoplasmic reticulum (ER) in skeletal muscle and is essential for calcium homeostasis. The mechanisms involved in SR remodeling and maintenance of SR subdomains are elusive. In this study, we identified myotubularin

Intracellular Ca(2+) ([Ca(2+)](i)) oscillations seen in interstitial cells of Cajal (ICCs) are considered to be the primary pacemaker activity in the gut. Here, we show evidence that periodic Ca(2+) release from intracellular Ca(2+) stores produces [Ca(2+)](i) oscillations in ICCs, using
