Can samples for the cAMP SPA screening assay kit (RPA556) be prepared without freeze drying equipment?
A. For use with the cAMP SPA screening assay kit (RPN556) we recommend freeze drying of samples be carried out using a dedicated freeze drying instrument. However, if this is not possible a Speed Vac evaporator instrument will be suitable for drying down samples. Keep in mind that this will likely take several hours and using a heated speed vac at the highest possible temperature would be best.
