Once plates are received, we freeze dry them for at least 36 hours. Once removed from the freeze drier, grinding beads are added, the plates are sealed and extracted. DNA pellets are dried overnight and rehydrated (if required) the next day. DNA is ready for testing the following day. So whether you send 1 96-well plate, or 100, it would normally take around a working week to return screening results (however, this process can be faster if required).
