Articles

Many metabolically important compounds, such as lipid-soluble vitamins and hormones, have very low solubilities in aqueous solutions. Various techniques have been used to solubilize these compounds in tissue culture, cell culture, or other water-based applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
