AccuSift provides high-performance Orange I (Acid Orange 7) 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.Orange I is an azo-based acid dye with relatively poor lightfastness, but produces bright coloration upon dyeing. It is used in the dyeing of wool, silk, nylon, and other textiles, as well as for coloring leather and paper. In biological staining, it serves as a protein stain and pH indicator (pH range 7.6-8.9). Due to its color stability, it has been illegally added to foods (such as chili powder and marinated products) for coloring; however, it is a non-edible substance and is strictly prohibited in food processing.Performance Specifications:
