Immunoprecipitation of I125-labeled DSD-1-PG with monoclonal antibodies. I125-labeled DSD-1-PG (106cpm/precipitation) was incubated with monoclonal antibodies 473HD, L2/HNK-1, L3, L4, and L5 as indicated, and immunoprecipitates were resolved on a 4–10% SDS-PAGE gradient gel. The first lane contains I125-labeled DSD-1-PG (5 × 104 cpm). An autoradiograph of the gel is shown.
