STATIC SEPARATION METHOD USING NON-POROUS CELLULOSE BEADS

摘要

An affinity separation method and system comprising an affinity separation media with low porosity and low non-specific binding, and a fluid containing a target compound to be isolated which is capable of binding onto the affinity separation media in a fluid mixing loop in a static filtration apparatus. The static filtration apparatus comprises an intermixing-chamber containing a filtration medium wherein a tangential flow is created for intermixing the affinity separation media and target compound in the fluid. The fluid is capable of passing through the filtration medium while the affinity separation media are substantially incapable of passing through the filtration medium. The affinity separation media are separated from the fluid by opening the filtrate outlet so as to allow the fluid to pass through the filtration medium of the static filtration apparatus. The filtrate can be thereby rendering substantially free of the target compound.
