Thermo Fisher, 1943452050, CaptureSelect™ Prothrombin Affinity Matrix

Quantity: 50 mL
Unit Size: Each
Prothrombin is a vitamin-K dependent plasma protein which is produced in the liver. The presence of calcium promotes the binding of prothrombin to phospholipid bilayers.Features of this affinity matrix include:
• Highly selective for human prothrombin without cross reactivity to other human plasma proteins
• Binds different forms of prothrombin (Factor II) in the presence of calcium
• Enables efficient purification of prothrombin with high yields and retained activity
• Mild elution at neutral pH using EDTA
• 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).Main characteristics:
