ryh1 Antibody

Definition and Overview of RyR1 Antibody

The RyR1 antibody is a highly specific immunological tool designed to target the Ryanodine Receptor 1 (RyR1), a calcium channel critical for excitation-contraction coupling in skeletal muscle. RyR1 is a ~560 kDa transmembrane protein localized to the sarcoplasmic reticulum, playing a central role in releasing calcium ions during muscle contraction . The antibody is commonly used in research and diagnostics to study muscle physiology, neuromuscular disorders, and immune system interactions .

Key Features of RyR1 Antibody:

• Epitope: Targets the N-terminal intracellular region, specifically residues 1371–1386 of human RyR1 .

• Host Species: Produced in rabbit (polyclonal) or mouse (monoclonal) systems .

• Applications: Validated for Western blot (WB), immunohistochemistry (IHC), immunofluorescence (IF), and immunocytochemistry (ICC) .

Structure and Function of RyR1

RyR1 forms a large ion channel complex with three B30.2/SPRY domains and five MIR domains, enabling calcium release from the sarcoplasmic reticulum . Its dysfunction is linked to:

• Malignant Hyperthermia (MH): Dominant mutations in RYR1 disrupt calcium regulation, causing lethal hypermetabolic crises during anesthesia .

• Central Core Disease: Congenital myopathy characterized by abnormal muscle fibers and impaired calcium signaling .

Applications of RyR1 Antibody in Research

The antibody is instrumental in studying:

Clinical Significance and Diagnostic Use

RyR1 antibodies are critical in:

• Genetic Testing: Identifying RYR1 mutations linked to MH and myopathies .

• Therapeutic Monitoring: Tracking calcium channel dynamics in neuromuscular therapies .
