As a coloring agent in the investigation of protein bodies, this substance has also found use.1 CARMINE. A solution of carmine in dilute potash, such as is sold by dealers, is used for staining the nuclei of cells.2 The solution, which should contain very little undissolved carmine, is filtered and then mixed with alcohol or glycerine in various proportions. The object requires to lie in the solution for some time. Only the nucleus (and protein grains) imbibe the color. The carminate of ammonium (ammonia carmine) is, however, more commonly used.3 It is prepared in the following manner, suggested by Hartig. Carmine powder is dissolved in a strong solution of ammonia until this is saturated; the solution is evaporated to dryness over a water bath, and the carminate thus formed is prepared for use by solution in water. 1 Wigand: Bot.

One part of carmine is dissolved in one part (by weight) of concentrated ammonia and three parts of distilled water. This solution is mixed with eight times its volume of dilute oxalic acid (i-.22). Twelve volumes of absolute alcohol are then added, and the whole is filtered. The filtrate may be rendered more orange in color .
