SPATIAL CONSIDERATIONS IN DISTRIBUTIONAL ANALYSIS: SOME ANALYTICS AND POSSIBLE APPLICATIONS TO VIETNAM

The visualization of RNA bands in denaturing electrophoresis gels is improved by staining the gels with a 2,7-diamino-10-(N,N,N',N'-tetramethyl-1,3-propanediamino)-propyl-9-phenylphenanthridine dihalide hydrohalide or a 2,7-diamino-10-[3-(diethylmethylammonio)propyl]-9-phenylphenanthridine dihalide. These dyes provide effective contrast for sensitive detection without the need for extensive washing of excess dye from the gels to lower background noise.
