Labeled SC35 pre-mRNA Splicing Factor in HeLa Cells

By Fluorescence:

Fluorescence micrographs of labeled HeLa cells (A) Stained with monoclonal primary antibody against SC35 pre-mRNA splicing factor, followed by secondary fluorescein and Nanogold-labeled anti-mouse Fab'; (B) Control stained with fluorescein and Nanogold-labeled anti-mouse Fab' only (Final magnification = 1,000 X, bar = 10 m).

By Electron Microscopy:

Transmission electron micrographs of labeled HeLa cells. (A) Stained with monoclonal primary antibody against SC35 pre-mRNA splicing factor, followed by secondary fluorescein and Nanogold-labeled anti-mouse Fab'; (B) Control stained with fluorescein and Nanogold-labeled anti-mouse Fab' only (Final magnification = 12,000 X, bar = 1 m).
