Ba contam in gut biopsy samples
From this I have a few questions:
1. Has anyone else used gut biopsy samples that might have thoughts? Are gut samples more prone to Ba contamination and we possible hit a bunch of “naturally” contaminated samples in a row?
2. Is it possible that a room/hood/space becomes contaminated and then can pass that contamination to samples that are processed there?
3. Has anyone seen a situation in which a few mild Ba signal reagents have combined to create massive contamination in the samples processed with them?
4. Is there a way to translate the levels of Ba signal in the reagents run as solution to expected levels of contamination in the cells?
Thanks for any help you might be able to offer.
