HiTrap Capto Q column

• Cat#No#: Hi-230P
• Product Overview: HiTrap Capto Q chromatography column is prepacked with a strong anion exchange modern resin for small scale protein purification.
• Characteristic: Suitable for screening selectivity, binding and elution conditions, and for small-scale purifications.
  Quaternary ammonium (Q) strong anion exchanger.
  Optimized for intermediate and polishing protein purification.
  Convenient HiTrap format for easy connection to a syringe, peristaltic pump, or chromatography system.
• Maximum operating pressure: 5 bar [0.5 MPa] (70 psi)
• Sample preparation: 1. Dilution of cell paste: Add 5–10 ml of start buffer for each gram of cell paste.
  2. Enzymatic lysis: 0.2 mg/ml lysozyme, 20 μg/ml DNAse, 1 mM MgCl2, 1 mM Pefabloc SC or PMSF (final concentrations). Stir for 30 min at room temperature or 4°C depending on the sensitivity of the target protein.
  3. Mechanical lysis: Sonication on ice for approx. 10 min, homogenization with a French press or other homogenizer or freeze/thaw, repeated at least five times.
  4. Adjust the pH of the lysate. The pH should be at least 0.5 units below (cation exchangers) or 0.5 units above (anion exchangers) the pI of the target molecule. Do not use strong bases or acids for pH-adjustment (precipitation risk). Apply the unclarified lysate on the column directly after preparation.
