AMBERLITE XAD-16 is a nonionic, hydrophobic, cross-linked polymeric adsorbent supplied as insoluble white beads. It is characterized by its macroreticular structure, which provides both a continuous polymer phase and a continuous pore phase, offering high surface area and porosity . This adsorbent is specifically designed to capture hydrophobic molecules from polar solvents and volatile organic compounds from vapor streams . It is ideal for use in column or batch operations and is effective for the adsorption of organic substances with relatively low to medium molecular weight . The product is widely utilized in applications such as the purification of antibiotics, recovery of water-soluble steroids, amino acids, and proteins, as well as the removal of nonpolar compounds from polar solvents .
HEPES buffer(4 ?C (2-hydroxyethyl) ?C 1-piperazine ethanesulfonic acid) is a zwitterionic sulfonic acid buffer; One of good??s 20 buffers. Hepes buffer is widely used in cell culture, mainly because it can maintain physiological pH value better than bicarbonate buffer, which is also commonly used in cell culture, although the concentration of carbon dioxide (produced by aerobic respiration) changes. Lepe Zuniga et al. An unwanted photochemical process in which hepes buffer produces hydrogen peroxide when exposed to ambient light is reported, which is not a problem in bicarbonate based cell culture buffer. Therefore, it is strongly recommended to place the solution containing hepes buffer in the dark as far as possible to prevent oxidation.
