“…The same trend can be noticed for Fe as well. Higher concentrations of K and Cl were also measured by other authors 34 in snap-frozen tissues in comparison to formalin-fixed, but here they seem comparable due to dilution effect in cryo samples (Fig. 4).…”
Even though measurements in cryogenic conditions are the preferred choice for single-cell and plant analyses, cryo-fixation of human or animal soft tissues for X-ray fluorescence analysis still remains challenging.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
