Yes Merck can use similar freezers. But do you know what the capacity is? the key difference is imo if we wanted to find out if Merck is the potential partner is how large the cryopreserve capacity. If out of a sudden Merck is building large cryopreserve freezers for 10 or 20 millions capacity then we know it is extra ordinary and what we suspected that Merck is the potential partner may be true. Imo.
