CaptureSelect C-tagXL MiniChrom columns are designed for bench-scale resin screening, process development, and sample preparation. These pre-packed columns are ready to connect and have the following features:

  • Dimensions of 1 mL (0.8 cm x 2 cm) and 5 mL (0.8 cm x 10 cm)
  • Direct connection to standard chromatography systems
  • Packed with CaptureSelect C-tagXL Affinity Matrix, offering high dynamic binding capacity and high resolution over a wide range of flow rates

The 1-mL columns can be used for quick screening of application feasibility and lab-scale purification on a convenient and easy-to-use pre-packed column. The 10-cm bed height of the 5-mL column allows initial process development on a bench scale.

CaptureSelect C-tagXL Affinity Matrix has a unique selectivity for a small 4-amino acid peptide tag (E-P-E-A, glutamic acid-proline-glutamic acid-alanine). CaptureSelect C-tagXL Affinity Matrix purifies the C-terminal tagged proteins with high affinity and selectivity, even in the presence of urea and guanidine HCl, from complex mixtures like cell culture harvests and periplasmic fractions in a one-step process. Mild elution conditions at neutral pH can be applied using magnesium chloride or propylene glycol, which ensures high-activity recoveries of pH-sensitive target proteins. The affinity resin 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.

Features of this 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-derived

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).
