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.
