Answer:Five separate HiTrap Capto Q columns, each with a 5 mL resin bed, are supplied.
Answer:Strong anion exchange via quaternary ammonium ligands retains appropriately negatively charged analytes under controlled pH and ionic-strength conditions.
Answer:The 5 mL prepacked beds allow repeatable capture or intermediate-purification experiments without packing chromatography columns in-house.
HiTrap Capto Q chromatography columns are designed for protein purification by strong anion exchange. This pack supplies five prepacked 5 mL columns containing Capto Q resin with quaternary ammonium binding groups. The format allows systematic evaluation of loading capacity, buffer conductivity and salt-elution conditions in larger small-scale preparations. Negatively charged proteins can bind when the mobile-phase conditions favor electrostatic interaction with the ligand, while other components may pass through or elute differently. Analyze collected fractions for recovery, purity and aggregate content as relevant to the purification objective. The package has a total of 25 mL of prepacked resin distributed among five separate columns, not a single 25 mL bed.
