Hello,

I recently started working with a group that handles a lot of pig plasma and serum. When preparing for assays, they've noted that on several occasions some of the samples will be partially coagulated upon thawing from -80C. There doesn't seem to be any rhyme or reason to it amongst samples as it occurs with multiple sample types from different studies. Has any one else seen this before and now how it may be prevented? Appreciate the community assitance!
