Description

CaptureSelect CH1-XL 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 D x 2 cm L) and 5 mL (0.8 cm D x 10 cm L)
• Direct connection to standard chromatography systems
• Packed with CaptureSelect CH1-XL 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 screenings 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 columns allows initial process development on a bench scale.

The CaptureSelect CH1-XL Affinity Matrix recognizes the CH1 domain of human IgG antibodies, thereby enabling purification of all Fab fragments, independent of the light-chain type (kappa or lambda) and without binding of over-expressed light chain and light-chain dimers. In addition, it can be used for the purification of human IgGs from all four subclasses (1, 2, 3, and 4).

Features of this affinity matrix include:
• Platform approach for purification of high quality and correctly assembled human Fab fragments
• No co-purification of over-expressed free light chains due to selectivity for the CH1 domain
• Elution possible at pH 4.0–4.5 with 50 mM acetate buffer
• Caustic cleaning with up to 50 mM NaOH
• Excellent scalability
• No cross binding to bovine IgG, therefore presence of fetal bovine serum is not a problem

Free of animal components
CaptureSelect products are affinity ligands created by a proprietary technology based on camelid-derived single-domain antibody fragments. The ligand is a 13-kDa single-domain fragment comprising the three complementarity determining regions (CDRs) that form the antigen binding domain, efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
