Thermo Scientific™ POROS™ CaptureSelect™ IgM-XL Affinity Matrix
Description
POROS CaptureSelect IgM-XL Affinity Matrix is intended for the purification of human IgM, with no binding to other immunoglobulins.
Features of this affinity matrix include:
- IgM purification from plasma and serum
- Purification of monoclonal IgM from cell cultures
- Efficient purification of IgM with high yields and retained activity
- Excellent scalability
- Non-animal derived
- High flow rates
- Cross-reactivity towards mouse and rat IgM
POROS CaptureSelect IgM-XL Affinity Matrix binds to the Fc part of IgM. The high selectivity and yields obtained using this affinity matrix enable a robust, fast, and efficient purification process with excellent purity obtained in one step.
Free of animal components
CaptureSelect products contain affinity ligands based on recombinant single-domain antibody fragments (VHH) created by a proprietary technology. The VHH affinity ligand is a 12 to 15 kDa fragment comprising the three complementarity-determining regions (CDRs) that form the antigen-binding domain, efficiently produced in the yeast Saccharomyces cerevisiae by a production process free of any animal components (animal origin-free).
