This is the protocol used by Anjali Bisaria for rapidly fixing yeast cells from chemostat cultures to image for both bud index as well as fluorescence.  We found that this protocol preserves both GFP and mCherry fluorescence.

Overview

This is the protocol used by P. Xu for fixing yeast cells for GFP fluorescence.

Materials

  • Yeast cells
  • Formaldehyde 37% (Sigma-Aldrich, #252549)
  • Phosphate buffered saline??

Protocol

  • 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.
