High efficiency small particles. Multiple pore sizes to cover broad range of molecular sizes. Single pore size to cover range of globular proteins/antibodies Page 6. Larger columns for fractionation

2 SEC Applications Non-Denaturing Conditions Separations Based on Size in Solution Impurity testing, aggregation g analysis (separation of monomer/dimer/aggregates) Molecular weight characterization over wide MW range (000 0M) possible Expression and folding studies Separation of Reaction Components and Products, (conjugates) Purification Desalting and salt exchange Collection of fractions under non-denaturing conditions Page 6 SEC Technique Technique is isocratic No interaction with the stationary phase Separation based on differences in size Eluent contains buffer and salt Technique does not denature proteins 0,000 µv 00,000 0,000 00,000 0,000 00,000 0,000 00,000 0,000 00,000 0,000 Decreasing size R&D Bio SEC.DATA Smaller molecules spend longer in the pores and elute later. Larger molecules spend less time in the pores and elute sooner. 0 RT [min] 0 Gel Filtration Standard ( vial diluted with mls of eluent) (Thyroglobulin, -globulin, ovalbumin, myoglobin & vitamin B)

3 Elution Profiles If sample molecules have the same molecular dimensions, they will coelute and may not be separated by this technique If two molecules have the same molecular weight but different size in solution they may be separated The calibration curve describes how different size molecules elute fromthecolumnandcanbeusedto determine molecular weight equivalents based on solution size Choose the Appropriate Pore Size Pore Size MW Range Typical Sample (Globular Protein) 00Å 00 00,000 Small proteins 0Å 00 0,000 Small proteins 00Å,000,0,000 Most protein samples 00Å,000,000,000 Larger proteins and antibodies 000Å 0,000 7,00,000 Very large proteins 000Å > 0,000,000 Very large molecules viruses Lower limit on this column is hard to define, Use only for special applications 6
