ChromaX® A20 Affinity Chromatography Column

ChromaX®A20 is a protein A affinity chromatography column designed to quickly and accurately determine the antibody concentration (or titer) in cell culture super-natant, which is developed by unique surface treatment technique and coupling technique using recombinant protein A as ligand and polystyrene divinylbenzene (PS-DVB) microspheres with a porous structure as filling carrier.

• Hydrophilic PS-DVB substrate, with the features of good rigidity, low back pres- sure, and fast mass transfer.

• Unique hydrophilic treatment technology with low non-specific adsorption en- sures the accuracy of antibody concentration test results.

• Ligand specific binding sites, high selectivity ensures the accuracy of concentra- tion determination results.

• Stainless steel column for direct use on HPLC.

• Fast and efficient, taking only 2 - 5 minutes to complete an analysis.

• Good linearity within the wide range of antibody concentration of 0.02 to 10 mg/mL

• Adopting alkali-tolerant protein A ligand allows for regenerating the chromato- graphic column with the 0.1 M NaOH solution.
