Uses
Brilliant Black BN has been used:
- in micronucleus and comet assays to evaluate its genotoxic effect.
- as a quenching agent in calcium mobilization assay.
- as a redox indicator in microbiological inhibition bioassay using Bacillus megaterium to detect tetracycline and macrolides in milk.
Uses
Black PN is a synthetic dye used in foods and cosmetics. Additive. Also used as a modulator of adenosine A1/A3 receptors as potential therapeutic agents for conditions involving metabolic stress.
General Description
Brilliant Black BN (BB) is a azo dye which is basically a tetra sodium salt. It is a synthetic dye mainly used as food additive. It is used as colouring agent to enhance the appearance. It is usually used in jellies, brown sauces and cake mixes.
Biochem/physiol Actions
[4-acetamido-5-hydroxy-6-[7-sulfonato-4-(4-sulfonatophenylazo)-1-naphtylazo], also known as food black 1, belongs to the group of azo dyes. Brilliant Black BN is widely used as a food dye and pharmaceutical excipient. In addition, it also acts as an allosteric modulator of the adenosine A1 and A3 receptors and is generally used within calcium mobilization assays to reduce extracellular fluorescence.
Properties and Applications
black. Soluble in water for dark purple, slightly soluble in ethanol for red light blue. The strong sulfuric acid for Tracy in blue, blue for red after diluted. The dye solution to join strong hydrochloric acid for navy, add thick sodium hydroxide solution for black purple.
