4.2 General Purification Protocol
Ion exchange chromatography is usually
performed using increasing salt gradients
or pH gradients to elute the sample
components. For best results and increased
cartridge life, samples and buffers should be
degassed and filtered through a 0.45 µm filter.
Common buffers are listed in Table 4.
