摘要:
The invention pertains to the dystrophin-glycoprotein complex of mammalian skeletal muscle and a method of isolating said complex. The components of the complex and methods of separating and isolating said components also pertain to the invention. In addition, the invention further relates to a method of diagnosing muscular dystrophy by detecting and quantifying the loss of a non-dystrophin component of the dystrophin-glycoprotein complex with said loss being indicative of muscular dystrophy.

摘要:
The invention pertains to pure, native dystrophin of mammalian skeletal muscle and a method of purifying dystrophin from mammalian skeletal muscle. The invention further pertains to a method of diagnosing muscular dystrophy by detecting the loss or abnormal structure of pure, native dystrophin from mammalian skeletal muscle. The detection of a loss of dystrophin or an abnormal structure of dystrophin is indicative of muscular dystrophy.

The present invention relates to a method of diagnosing malignant hyperthermia susceptibility by detecting abnormal ryanodine receptor fragments following proteolytic enzyme digestion of ryanodine receptors isolated from the sarcoplasmic reticulum of mammalian skeletal muscle. The detection of abnormal ryanodine receptor fragments is indicative of malignant hyperthermia susceptibility.

摘要:
Disclosed is a novel photo-activatable derivative of ryanodine 9-hydroxy-21-(4-azidobenzoyloxy)-9-epiryanodine. This novel ryanodine derivative has been conjugated to keyhole limpet hemocyanin (KLH) and used for the production of antibodies with high affinity and specificity to ryanodine. A radioimmunoassay specific for ryanodine was developed using the anti-ryanodine antibodies, and a dissociation constant for ryanodine of 1 nM was determined. Also disclosed is the binding of a labeled, photoactivatable derivative of ryanodine (ABRy) with the ryanodine receptor of skeletal, cardiac and brain membranes. Digestion of the labeled ryanodine receptor revealed a labeled 76 kDa tryptic fragment which is critical for the formation of the high affinity ryanodine binding site.
