In this video, we demonstrate the technique to isolate baculovirus from an insect cell supernatant using heparin affinity chromatography. The isolation is facilitated by the affinity between the heparin in the column to the baculovirus envelope glycoprotein.
Protocol
1. Preparation of the Chromatography System Prepare the chromatography system by sequentially rinsing the sample and buffer lines each with sterile water, 1 N sodium hydroxide, water, and wash buffer (20 mM sodium phosphate buffer containing 150 mM sodium chloride, pH 7.0) at a linear flow rate of 50 mL/min. Prepare a heparin 50 µm column (10 × 10 cm, 7.9 mL of column volume (CV)) by sequentially running column cleaning buffer (5 CV sterile 20 mM sodium phosphate buffer containing 2 M sodi…
