"Resource 15 Q (GE Healthcare Life Sciences) is an anion-exchange resin used for purification of proteins and peptides. The resin is positively charged so the proteins with negative charge bind to it which can then be eluted by a linear or non-linear gradient of salt. The binding capacity is 50 mg. I recommend it to use for proteins and peptides purification. "
The small (15 µm) monodisperse bead give high-resolution purification at high flow rates. In addition, hydrophilization of the beads minimizes nonspecific adsorption and allows high recovery of purified sample. The material of the column body is PEEK (polyetheretherketone). SOURCE 30Q and 30S media with a 30 µm bead size are designed for intermediate purification and large-scale polishing and allow higher flow rates.
