I am doing a Mass Spec experiment to compare proteomes of healthy Tardigrades and Tardigrades in their "tun" formation.

There are several different protocol for desiccating he tardigrades, usually involving placing them on agar plates and then putting them in a humidity chamber. But the biggest issue I am facing is that I don't know how to physical collect the Tardigrades once they have formed the tuns.

Is there any option other than physically scrapping or selecting them? Maybe wash them with ethanol than evaporate it off?

Any help is much appreciated
