Thermo Scientific Pierce Cellulose Acetate Filter Spin Cups are convenient tools for manipulating small volumes of affinity supports (20 to 400 μL) for protein purification.
Features of Cellulose Acetate Filter Spin Cups:
• Smaller pore size: cellulose acetate filters have smaller pore sizes than paper • Column volume: 800μL • Resin volume: 20 to 400μL • Filter type: cellulose acetate filter, 0.45μm pore size • Cap: collection tube cap fits onto inserted spin cup
Simply add the affinity resin and sample to one of the spin cups, then use a microcentrifuge to efficiently wash away contaminants and elute your purified sample without losing any resin in the process. Spin cups allow you to affinity purify more protein in less time.
