<p>
 SKBR-3, a breast cancer cell was prepared on a hemocytometer and observed under Foldscope. Trypan blue staining was done and both viable and dead cells can be seen.
</p>
<p>
 Procedure:
</p>
<p>
 (1) Place 100 µl of cell
suspension in a cryo-vial.
</p>
<p>
 (2) Add equal parts of 0.4%
trypan blue dye to the cell suspension to obtain a 1 to 2 dilution (example: 50
µl of cells to 50 µl of trypan blue) and mix by pipetting up and down.
</p>
<p>
 (3) With the cover slip already
in place, fill one side of a hemacytometer counter with the cell suspension by
placing the tip of the pipette at the notch.

 Blue cells are the nonviable
cells.
