Table 2. Myofibrillar ATPase Activity and Myosin Isozyme Distribution in the Hearts of Different MH-genotyped Berkshire Pigs
Animals were genotyped by Hal-1843 nucleotide examination. Cardiac myofibrillar adenosine triphosphatase (ATPase) activity at pCa 4.0 (−log[Ca2+]) was assayed as described in the Methods. Cardiac myosin isozymes were analyzed by pyrophosphate-containing gel electrophoresis according to Hoh’s method. Values are mean ± SD. Numbers (N) of animals studied are indicated. Each animal contains at least three measurements.
MH = malignant hyperthermia; Pi = phosphate.
