Abstract:Bovine blood samples with ethylene diamine tetra-acetate (EDTA) or oxalate as anticoagulant were stored at refrigeration temperature of 4°C. The packed cell volume (PCV) was determined daily. During storage, the PCV did not vary significantly. Complete haemolysis, suggested by failure of blood samples to separate into cellular and plasma fractions, started occuring in samples on days 28 and 17, and was observed to have occurred in all samples on days 41 and 24 in blood with EDTA and oxalate respectively.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
