Immunohistochemistry (frozen & paraffin)
CA 19-9 antibody reacts strongly positive with most tumour cell lines of gastrointestinal carcinoma including adenocarcinoma of the stomach, intestine, and pancreas. Positive reactivity was also found in transitional cell carcinoma of the bladder, adenocarcinoma of the endometrium and the gallbladder as well as in papillary carcinoma of the thyroid glands. Last but not least positive reactivity of lung carcinoma must be mentioned (adenocarcinoma, bronchio-alveolar carcinoma, squamous epithelial carcinoma, and SCLC). Sialyl Lewis a antigen is an oncofetal antigen, which appears during early development of the gastrointestinal tract. After birth it is still detectable in ductus and secretion of intestinal glands, respiratory and reproductive tract. In normal tissue Sialyl Lewis a (CA 19-9) is found in ductal epithelia of the breast, kidney, salivary glands, lung, colon, bile duct, liver, pancreas and prostate gland. Sialyl Lewis a antigen (Cancer Antigen CA 19-9).
Immunogen: Immunodiffusion precipitate of ovarian cystic mucins with NS19-9-antibody
Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 100 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art .No. PU002.
Purification Method: Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 100 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art .No. PU002.

Secondary Reagents: As secondary reagents we recommend the use of biotinylated anti-mouse IgM antibody (Art. No. BA-2020) in combination with streptavidin conjugates or ABC systems.
Species Reactivity: Human
ELISA, IRMA, IHC (cryostat and paraffin sections)
Incubation Time: 60 min at RT
Working Concentration: (liquid conc.) 1:10 - 1:50
Pre-Treatment: In paraffin section no pre-treatment is required, however heat induced antigen retrieval may improve the staining. Each laboratory should select it's own optimum staining and pre-treatment conditions.
Positive Control: Colon carcinoma
