Assessment of O[sub 2] uptake dynamics in isolated single skeletal myocytes.

Describes a technique for rapid measurement of O[sub 2] uptake dynamics in isolated single skeletal myocytes. Measurement of O[sub 2] uptake in isolated Xenopus laevis myocytes using a phosphorescence quenching technique; Monitoring of the fall in extracellular PO[sub 2] which is proportional to cellular O[sub 2] uptake.
