Flotation results indicate that PIONERA BioPolymers, at each dosage, significantly reduce pyrite than conventional pyrite depressants. Additionally, conventional pyrite depressants such as sodium cyanide, sodium hydro sulfide and Nokes reagent are toxic, highly regulated, difficult to handle and present an overall costly alternative.
Our lab has focused specifically on the role of lipid droplets and lipidrich membranes in the life cycle of HCV. To analyze the role of lipidrich membranes in HCV RNA replication, we utilized a membrane flotation assay based on an 102030% iodixanol density gradient developed by Yeaman et al. (2001). This gradient results in a linear increase in density over almost the entire length of the gradient, and .
