Background:        CA19-9 has been the most valuable serum biomarker in monitoring progress and regression of pancreatic cancer and colorectal cancer.  CA19-9, also known as sialyl-Lewisᴬ, is a tetrasaccharide which is expressed in abundance on the surface of cancer cells. CA 19-9 usually ranges from 0 to 37 units per milliliter in a healthy person. CA 19-9 levels can be higher in patients with pancreatic cancer and other cancers.

Applications:         

Indirect ELISA: CA19-9 mAb clone 9B2 at a wide concentration range can react with ELISA plate coated with SW1116 and also with ELISA plate coated with purified CA19-9 at 0.125 KU per well.

Sandwich ELISA: CA19-9 mAb clone 9B2 can be used as detection antibody in Sandwich ELISA when anti CA19-9 clone 4E11 (Cat. No.: MO-T40015D) is used as capture antibody.

Immunohistochemistry (IHC): CA19-9 mAb clone 9B2 was used to stain pancreatic cancer tissue and paracancerous tissue. Briefly, the paraffin sections of pancreatic cancer tissue and paracancerous tissue were treated with EDTA to re-naturalize antigen epitopes and with 3% H2O2 to remove endogenous catalase. The sections were blocked with goat serum, incubated with 1:500 diluted CA19-9 mAb 9B2 overnight at 4℃ and washed, followed by incubation with HRP-conjugated goat anti-mouse IgG. Sections were stained with DAB and counter-stained with Hematoxylin.
