Witrynaimpurity clearance. However, acidic and neutral antibodies (isoelectric point [pI]) ≤ 8.0), may have solubility issues at low ionic strength conditions. For these antibodies, it is often challenging to achieve adequate clearance for HCP and viruses when buffer conductivity is increased to favor antibody solubility (internal unpublished data ...
