From: Force produced after stretch in sarcomeres and half-sarcomeres isolated from skeletal muscles
Half and single sarcomere isolation.
A - Glass micro-needles approaching a single myofibril on the microscope coverslip (magnification = 90X). B - Half-sarcomere caught between the micro-needles. The myofibril is still on the coverslip (magnification = 90X). C - Half-sarcomere isolated and lifted (~2 μm) from the coverslip (magnification = 150X). D - Single sarcomere caught between two micro-needles (c).
