生物活性

Allura Red AC is a food colorant, appearing as a deep red water-soluble powder or granules, used in various applications such as beverages, syrups, candies, and cereals. Allura Red AC can statically quench the intrinsic fluorescence of HSA. Additionally, Allura Red AC is a 5-hydroxytryptamine (5-HT) pathway-associated pro-inflammatory agent, capable of exacerbating experimental colitis. Allura Red AC holds potential for research in inflammatory bowel disease (IBD), intestinal barrier function, and food additive safety[1][2][3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
