Aggregation of therapeutic proteins can result in an incorrect drug dosage, or and undesired and potentially fatal immune response. Consequently, monitoring protein aggregates is important for safety and quality assurance.
Investigators routinely use size-exclusion chromatography (SEC), which separates particles according to hydrodynamic size. Recently the use of hydrophobic interaction chromatography (HIC) has also received great interest as an orthogonal technique to SEC.
HIC separates proteins based on the hydrophobicity in the native state and can often detect changes in protein structure as well as aggregates.
Use Thermo Scientific MAbPac SEC-1 Size Exclusion Columns for high-resolution separation of monoclonal antibody (mAb) analysis, including the monomers, aggregates and Fab and Fc fragments resulting from proteolysis. These size exclusion chromatography (SEC) columns provide superior performance, even under non-denaturing conditions, and in high- and low-salt mobile phases and volatile eluents.
Now you can use a column specifically designed for the separation of monoclonal antibodies (mAbs) and related biologics by hydrophobic interaction (HIC). The Thermo Scientific MAbPac HIC-10 LC high- resolution silica column has a unique chemistry that provides excellent biocompatibility, and selectivity that is different from other HIC columns on the market. Unlike SEC columns, this column separates by hydrophobicity and resolves the different isomeric forms of higher order structures.
