Immunoprecipitation of the AM surface protein recognized by mAb PAL-1. Hamster AMs were surface-labeled with sulfo-NHS-biotin, extracted with Triton X-100, precleared with anti–mouse IgM magnetic beads, and immunoprecipitated with mAb PAL-1 or a control IgM bound to anti–mouse magnetic beads. Immunoprecipitates were analyzed using reducing (R) or nonreducing (NR) SDS-PAGE as described in Materials and Methods. Relative molecular mass is indicated (kD).
