CA19-9 Antibody & ELISA
The CA19-9 (sialyl-Lewisᵃ) product line offers reliable tools for carbohydrate antigen and glycoprotein research. This range includes high-quality monoclonal antibodies such as Clone 4E11 (capture) and Clone 9B2 (detection), designed for clean, consistent performance in sandwich ELISA and other immunoassays.
These antibodies form the core of the Human CA19-9 ELISA Kit, which provides a fast 2.5-hour workflow, a detection limit of 1.7 U/mL, and strong lot-to-lot reproducibility.
