Document Type Product Information Sheet. Product Name Carmine Alum. Carmine has been used in biological staining to demonstrate selectively nuclei, chromosomes or mucins, depending on the formulation. Throughout its history in science, complaints and frustrations have been expressed about dye quality.
Inconsistencies in dye quality or identity have prevented thorough understanding of staining mechanisms and have caused many stain solutions to behave unsatisfactorily. The aim of this review is to 1 detail causes of these problems, which are rooted in history, geography and production, 2 offer ways to minimize problems and 3 provide modern explanations for stain behavior.
Carmine is a "semi-synthetic" dye, i. Carmine shows considerable batch-to-batch variability. Geography, politics, history, agricultural practices and iconography all contribute to the variability of cochineal.
In addition, widely divergent manufacturing methods are used to produce carmine. Also, confusion in terminology has led to mislabeling. Pressure from the food industry for a more satisfactory colorant for acidic foods led to the introduction of a new dye, aminocarminic acid, which could enter the biological market inadvertantly. Improved methods of analysis should help the certification process by the Biological Stain Commission.
Further standardization could be achieved by replacing most of the methods of solubilizing carmine.
