This is the protocol used by P. Xu for fixing yeast cells for GFP fluorescence.
- Yeast cells
- Formaldehyde 37% (Sigma-Aldrich, #252549)
- Phosphate buffered saline??
- Prepare eppendorf tubes with 50μL of 37% formaldehyde, one per sample.
- Add 450μL of culture to 50μL of formaldehyde in an eppendorf tube and mix by inversion. (The goal is to have a final concentration of formaldehyde around 3.7%. So you can adjust the cell and formaldehyde volumes accordingly, as long as you end up with 3.7% formaldehyde).
- Incubate the tube at room temperature for 15-20 minutes.
- Spin down ??
- Resuspend cells in ??
- Store samples at 4°C until you are ready to image.
