IN a recent communication 1 Goldstein suggests that differential staining of DNA and RNA can be obtained by a number of binary mixtures of basic dyes, of which the dye with the higher molecular weight ...

Recently we have done two differential stains, the Gram stain and the Acid Fast stain. Both stains differentiate between bacteria chemically. The two staining techniques of Lab 4 differentiate by ...
