Description
Quantity: 1 Strip (8 Pieces), 200 μL
Unit Size: Each
The CaptureSelect C-tagXL Affinity Matrix in this RoboColumn recognizes the E-P-E-A tag sequence when fused either directly to the C-terminus of a protein or through a linker between the C-terminus and the E-P-E-A tag. CaptureSelect C-tagXL Affinity Matrix purifies C-terminal tagged E-P-E-A proteins directly from complex source materials in a single step with high purity and yield.Features of C-tagXL Affinity Matrix include:
• Mild elution, making it suitable for pH-sensitive proteins
• Binding of the tagged proteins under denaturing conditions (like dissolved inclusion bodies)
• 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
