2).Will it work with my special cell line?

There’s no reason why the Cells-to-CT system shouldn’t work with any cell line. (Please refer to the table above for cell lines tested and confirmed to be compatible). However, due to differences in cell size and composition, the maximum number of cells per lysis reaction may be slightly different for different cell lines. Testing for inhibition and minimal sample input by using he TaqMan Cells-to-CT Control Kit.

3).  Why do you say this is a “green’ alternative to standard purification?

Less waste, less hazardous - 10 Sample Comparison

RNeasy

140 g plastic waste
18 mL hazardous waste
Cells-to-CT

4).  How do I remove gDNA from my Cells-to-CT reaction?

  1. Ensure all media is removed from the wells.
  2. Wash with an equal volume of room temperature 1X PBS after the media removed.
  3. Ensure reaction happens at room temperature (lysis reaction may not reach room temperature if plate is on ice, quickly moved to bench, or cold lysis solution is added).
  4. Warm lysis solution to room temperature before adding to cells
  5. Allow lysis reaction to proceed for 8 minutes.
  6. Perform lysis reaction at 25°C for up to 8 minutes.
