AccuSift provides high-performance Orange II 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 II, chemical name sodium 4‑[(2‑hydroxynaphthalen‑1‑yl) diazenyl] benzenesulfonate, is used for dyeing wool, silk, leather, nylon, and paper, and as a biological stain and indicator.This dye is listed in the "List of Non‑edible Substances Possibly Illegally Added to Foods and Easily Abused Food Additives" as a non‑edible substance, strictly prohibited in food processing. Long‑term consumption may increase cancer risk. Unscrupulous vendors take advantage of its bright color, strong tinctorial strength, and low cost to add it to chili powder, marinated meats, and other processed foods to enhance their appearance.Performance Characteristics:
