Dialysis method for protein purification
WebUse of dialysis cassette for protein cleanup. 3 mL of 1 mg/mL IgG in 0.1 M Tris buffer, pH 7 inside a dialysis cassette is placed in 1,000 mL of 100 mM PBS, with a pH of 7.6. The old dialysate is discarded and replaced with 1,000 mL of 100 mM PBS, with a pH of 7.6. IgG is too large to enter the pores in the membrane; therefore, the amount of ...
