 **Add ~100 uL cells under coverslip to hemocytometer.
 **Count one row of 4 squares.  For cells touching the edges of the square, only count the top and left line to avoid counting the same cells twice.
-**Record the number of cells (should be 30-150 cells per row) and Calculate cell concentration, where \alpha is number of cells per row

+**Let cells attach for >30 min, then add 0.5mL fresh media with 10 ug/mL dsRNA
+**Refeed cells with fresh media and dsRNA daily, typically for 4 days.
