Immunoprecipitation of scFv-CD20–β-glucuronidase. COS-7 cells were transfected with scFvCD20-β–glucuronidase or β-glucuronidase cDNA. The cells were labeled 48 hours after transfection with 35S-methionine/cysteine for 4 hours, the supernatant was immunoprecipitated with rabbit anti-β–glucuronidase antibody and analyzed by SDS-PAGE.
