Immunoprecipitations were performed as described in Materials and methods, and as shown in Fig. 6 D. X indicates a positive result as defined for the following specificities: RNP, immunoprecipitation of A, B′/B, C, D, E, F, and G, but not U5 200K protein; Sm, immunoprecipitation of A, B′/B, C, D, E, F, and G plus U5 200K protein; Ro60, immunoprecipitation of 60 kD protein; La, immunoprecipitation of 45 kD protein; Core histones, immunoprecipitation of H2A/H2B plus unidentified band; RNAPII, immunoprecipitation of RNA polymerase II, two largest subunits; DNA-PK, immunoprecipitation of DNA-PKcs, Ku70, and Ku80 proteins; OJ, immunoprecipitation of multiprotein complex.
