AccuSift High-Performance Carmoisine (Azorubine) Competitive Assay PairAccuSift provides high-performance carmoisine (Azorubine) competitive assay pairings, characterized by exceptional batch-to-batch consistency and optimized for IVD kit development (Lateral Flow, Chemiluminescence, ELISA, POCT). These pairings offer high affinity and specificity, facilitating rapid detection.Carmoisine is a synthetic azo‑based red food color, soluble in water, red in ethanol, and slightly soluble in acetone. It appears red under acidic conditions, turning yellow or orange‑yellow in neutral to alkaline conditions.The compound is mainly used for dyeing and direct printing of wool, silk, and nylon, and finds applications in leather, paper, foil, inks, wood products, biological products, cosmetics, pharmaceuticals, and food coloring. Its heavy‑metal salts are used as organic pigments. Combined with Acid Blue A, it yields Acid Mordant Dark Blue AGLO.According to the World Health Organization’s International Agency for Research on Cancer (IARC) preliminary compilation dated October 27, 2017, Acid Red 14 (Carmoisine) is listed as a Group 3 carcinogen.Performance Characteristics:
