Fill the syringe or pump tubing with de-ionized water. Remove the stopper and connect HiTrap™ column to syringe (use the connector supplied).
Snap off tab on the column outlet.
Wash out the ethanol with 26 ml of de-ionized water.
Equilibrate column with 26 ml of binding buffer. The recommended flow rate is 5ml/min.
Apply the IgY sample using a syringe fitted to Luer connector or by pumping it onto the column.
For better results, use a flow rate of 0.5 to 5.1 ml/min during sample application.
Wash with at least 51 ml of binding buffer or no material remains in the effluent.
Maintain a flow rate of 5 to 11 ml/min for washing.
Elute with 51 ml of elution buffer using a one-step or using a linear gradient though larger volumes are often required to break the interaction.
After elution, regenerate the column by washing with 36 ml of wash buffer.
Re-equilibrate the column with 26 ml of binding buffer.
The column is now prepared for a new purification.
