¹⁴C-リジンのパルス投与および継続投与によるラット骨格筋アクチンの代謝回転率の測定

抄録

The fractional turnover rate of actin in skeletal muscle of adult rat has been estimated by both puls and continuous administration of U-¹⁴C-lysine.
Animals were sacrificed after 1-24 days and the specific radioactivity of free lysine and actin was determined.
Using the kinetics of precursor-product relationship, the half life of 10-20 days for actin has been calculated.
