Tether Pulling of Macrophage Cell by Optical Tweezers from JPK Instruments
This video shows the pulling of membrane tether from the macrophage cell by optical tweezers from JPK Instruments. A membrane tether is pulled using an amine-modified bead from a macrophage.
The amine-modified bead is trapped and brought in contact with the cell membrane. The membrane tether is pulled out of cell by moving the bead away from the cell. The bead is pulled backward to the cell by the tether after the optical trap is turned off.
