POROS CaptureSelect FibXL Affinity Matrix has specifically been designed for the purification of human fibrinogen from recombinant or plasma source.

Features of this affinity matrix include:

• Fibrinogen purification from human plasma and recombinant sources
• Efficient purification of fibrinogen with high yields and retained activity
• Excellent scalability
• Non-animal derived
• High flow rates

POROS CaptureSelect FibXL Affinity Matrix is an affinity matrix that binds to fibrinogen with high selectivity and yield, enabling 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).
