[Nhcoll-l] freezing of dried algae specimens

[Tocci, Genevieve E.]

Hi Eirik,

If you follow standard freezing protocols it poses no problems for algae. We do this all the time. I do recommend having them in a bag of some sort and letting them fully thaw after treatment. I also recommend against freezing microscope slides or mica slides when possible.

Best wishes,
Genevieve

Dear all,

I was wondering if anybody have any experience with freezing dried algae specimens for pest control. Will this adversely affect the specimen?
