| 2. Can you clean affinity resins with caustic? |
Toyopearl AF-Chelate-650M and, in extreme cases where other reagents do not remove residual protein, Toyopearl AF-Heparin HC-650M, can be cleaned with caustic up to 0.5 M NaOH. All other Affinity products such as the activated media are most likely sensitive to caustic (due to the nature of the attached ligand) and should be cleaned with less aggressive combinations of salt, chaotrope, & detergent.
