Application Notes
2010
The demand for monoclonal antibodies is invariably increasing on an annual basis. To satisfy increasing demands, faster and cheaper ways of manufacturing are explored. A quest for alternative paths in manufacturing not only requires development of most economical manufacturing process, but also rapid method development and development of good analytics for monitoring of manufacturing. For a quickly developed process, the use of reliable and fast analytical techniques are crucial. Moreover, this analytical technique should than be preferably used also for in-process control during manufacturing stage.
Here we present fast and reliable method for processing and analyzing IgG, IgA ang IgM using CIM® QA Disk Monolithic Column, which thrive upon speed, repeatability and high capacity.

A Hemoglobin A1c reference standard was loaded on CIM® SO3 monolithic column and eluted in a mixed stepwise and linear gradient. HbA1a, HbA1b and HbA0 variants were separated and a complete determination of HbA1c (including equilibration) was obtained within 1.1 minute.

A mixture of IgG, HSA and IgM standard was loaded on CIM® EDA Disk and eluted in linear salt gradient at a flow rate of 4 mL/min (12 CV/min). A complete separation of IgM from IgG and HSA was obtained within 1.5 minute.

Immunoaffinity columns were prepared by immobilization of Protein G on CIM® Epoxy Disk, CIM® Epoxy tube (1 mL) and an activated, particle based agarose support. A comparison of productivity was performed by loading centrifuged human plasma and resulted in superior productivity of CIM® monolithic supports.
