Is it possible to use frozen cell pellets with the FastLane Cell cDNA Kit?

Yes, it is possible to process frozen cell pellets with the FastLane Cell cDNA Kit. Follow Appendix D protocol 'Processing Suspended Cells' in the FastLane Cell cDNA Handbook, starting from step D3. In our R&D labs, we let the pellet stand for 30 seconds at room temperature, add wash buffer FCW, spin down the cells promptly, and aspirate the wash buffer. In general, cells should not be vortexed or pipetted up and down during the wash step, and they should not be incubated in buffer FCW.

Note that it is essential to wash the cells with Buffer FCW at step D3. Omitting this step, or washing with PBS only, will inhibit subsequent steps in the protocol.
