Figure 1.
(A) The solubility of CO in UW solution at 4°C after 5 minutes bubbling with different concentrations of CO gas. (n=3 for each concentration) CO solubility rises in a dose dependent manner. (B) Sequential analysis of CO content in UW solution after 5 minutes bubbling with 100% CO gas with or without secured, air-tight lids. CO levels were maintained as long as 24 hours when the container of UW solution was sealed without air-phase (closed circle, n=3 for each time point). However, CO concentrations decreased quickly when CO-bubbled UW was exposed to air. (open circle, n=3)
