Description
Quantity: 1 Strip (8 Pieces), 200 μL
Unit Size: Each
The CaptureSelect AAT-XL Affinity Matrix in this RoboColumn has been specifically designed for the purification of native human alpha-1 antitrypsin (AAT) from complex sources like plasma/serum and recombinant human AAT from cell culture supernatants. The high selectivity and yield obtained using CaptureSelect AAT-XL Affinity Matrix enable a robust and efficient purification process with excellent purity obtained in a single step.Features of this affinity matrix include:
• Highly selective for native and recombinant human AAT
• High recovery and yield obtained in a single purification step
• Mild elution at pH 6
• Excellent scalability
• Non-animal-derivedFree of animal componentsCaptureSelect 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).Characteristics
