Yes, me too. But since you said you could use it, then I believe it is same case as the "tissue samples" from the Feaster of Souls quest.
For those who don't remember: in one of the first missions, you have to walk in a fungus floor that deals damage to you. Once you received damage, you could use a Scalpel to get a sample of the floor, and then bring 20 samples to the NPC. In this quest, if you tried to delived Samples cut by other players, it would not work. I guess it might be same case in deepling crates here.
