The size of PureCube Ni-NTA agarose resins ranges from market standard 40 and 100 µm diameters to 400 µm (XL). These three options provide plenty of possibilities to choose the correct agarose resin for your purpose. Choose smaller beads for higher mechanical stability and higher protein yield. Meanwhile, bigger beads provide faster flow rates and the possibility of working with very viscous cell media.
