Mouse Monoclonal, RTU. Intended for in vitro diagnostic (IVD) use. This antibody is a broad-spectrum keratin antibody cocktail composed of AE1 that recognizes acidic type I keratins 10, 14, 15, 16, 19, and AE3 that recognizes basic type II keratins 1, 2, 3, 4, 5, 6, 7, and 8. This antibody detects carcinomas of different organ origin and is useful in the classification of tumors of epithelial origin and undifferentiated carcinomas. References 1. Battifora H.
