WebDBC over time (2). Historically, Protein A chromatography resins have been sensitive to NaOH due to the limited alkaline stability of the protein ligand. Later generations of Protein A resins exhibit improved alkaline stability and have recommended cleaning procedures using 0.1 M NaOH, with the option of occasional use of 0.5 M NaOH. Webing the DBC [2–5] and rendering it nearly insensitive to the flow rate. Regardless of the type of support, a chromatographic separation can be performed using two elution modes: negative mode or flow-through chromatography, and positive mode or bind-and-elute chromatography. In the first mode of operation, impurities are
