Gliding Motility Assay
- This entry describes the procedure in the Gliding Motility Assay
Procedure
- First turn on the mercury lamp and prepare the microscope for Kohller Illumination.
- Polymerize the microtubules (Procedure can be found here: Microtubule polymeration).
- In the 30 minute wait for the polymerization of the microtubules, one can prepare the following solutions:
- 0.5 mg/mL of α-Casein in PEM: 500 µL of 1mg/mL α–Casein in PEM and 500 mL of PEM.
- PEM–αA: 1µL of PEM-A and 99 µL of 0.5 mg/mL of α-Casein in PEM.
- Kinesin in PEM-αA: 2 µL of Kinesin with 18 µL of PEM-αA.
- In a flow cell, let 10 µL of 1mg/mL α–Casein in PEM rest for 10 minutes.
- During this 10 minutes, prepare the Motility solution (Procedure can be found here: Motility solution).
- After the 10 minutes are up, exchange the fluid on the cell with the solution of Kinesin in PEM-αA, and let it incubate for 5 minutes.
- After those five minutes, exchange the fluid on the cell with 20 µL of the motility solution.
- Finally, seal the end of the sample section on the flow cell with nail polish.
