Isotype

Mouse IgG1

Specificity

The mouse monoclonal antibody 7LE recognizes Lewis^a blood group antigen, a carbohydrate determinant carried on both glycolipids and glycoproteins, expressed on colonic epithelial cells. Lewis^a may be useful for detection of gastrointestinal, pancreatic and colorectal tumors.

Application

ELISA, WB, IHC(P)

Application details

Immunohistochemistry (paraffin sections): Recommended dilution: 5 μg/ml; positive control: colorectal adenocarcinoma; heat mediated antigen retrieval (sodium citrate); mAb incubation 1 hour / RT, detection DAB.

Reactivity

Human

Immunogen

Mucin isolated by size-exclusion chromatography from an ovarian cyst fluid (pure endocervical type according to the Fenoglio´s classification).

Concentration

1 mg/ml

Preparation

Purified by protein-A affinity chromatography.

Formulation

Phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide

Storage and handling

Store at 2-8°C. Do not freeze.
