to see , how the isolated contractile system is affected by an increase in the light chain phosphorylation , tension transients were studied in skinned right ventricular muscle fibres before and after incubation with atp gamma s ( 2 mm ) , pure myosin light chain kinase ( 9 micrograms/ml ) , calmodulin ( 1 microm ) and ca2+ ( 0.8 microm ) .
