Intermediates and products of the processing reaction associate with Sm proteins. After 2 or 45 min of incubation, RNAs were immunoprecipitated with various antibodies (see text and Materials and Methods). T (total) represents
of the amount of RNAs used in each reaction. The other lanes contain RNAs isolated from immunoprecipitates. Shown is an autoradiograph of a 6% acrylamide gel. Legends as in Fig. 1B.
