Rat portal veins were chemically skinned using Triton X-100 and mounted for isometric and quick release experiments at 20°C. The skinned preparations were activated by Ca2+ (EGTA-buffered) in solutions containing 2 mM free-Mg2+ and 1 μM calmodulin. Half maximal isometric force was obtained at pCa=6.2. Maximal force of the skinned preparations, at pCa=4.5, was 8.2±0.8 mN/mm2 (n=6). Force-velocity relations were determined at varied Ca2+-concentrations. Maximal shortening velocity (V max) was 0… CONTINUE READING
