Small nuclear RNAs from Drosophila KC-H cells; characterization and comparison with mammalian RNAs.
Small molecular weight nuclear RNAs were extracted from cultured Drosophila KC-H cells and characterized by their electrophoretic mobilities in 5--15% gradient acrylamide gels or in 10% acrylamide-7 M urea gels. Comparison between the electrophoretic profiles of these SnRNAs with those from human and mouse cells revealed striking similarities and allowed for assignation of band nomenclatures as established for mammalian cells. Comparison of mobilities in the two gel systems also permitted correspondence between the different nomenclatures established by various groups for this class of RNAs, as well as an approximate estimate of their molecular sizes.
