Product Summary for Lewis A Blood Group Antigen Antibody (SPM522) - Azide and BSA Free

Immunogen

Mucins isolated from ovarian cyst fluid

Localization

Cell membrane, cytoplasmic and extracellular

Specificity

Recognizes a carbohydrate determinant of Gal 1-3(Fuc 1-4) GlcNAc which is blood group antigen Lewis A. It is present primarily on epithelial cells such as colon and kidneys. In the tumors and dedifferentiated tissues, decrease of Lewis A antigen was observed. Lewis A (type 1 chain) is expressed in colonic epithelial cells and may be useful for detection of gastrointestinal tumors, pancreatic cancer, and colorectal tumors. Blood group related antigens represent a group of carbohydrate determinants carried on both glycolipids and glycoproteins. They are usually mucin-type, and are detected on erythrocytes, certain epithelial cells, and in secretions of certain individuals. Sixteen genetically and biosynthetically distinct but inter-related specificities belong to this group of antigens, including A, B, H, Lewis A, Lewis B, Lewis X, Lewis Y, and precursor type 1 chain antigens.

Applications for Lewis A Blood Group Antigen Antibody (SPM522) - Azide and BSA Free

Application
Recommended Usage

Flow Cytometry

0.5 - 1 ug/million cells in 0.1 ml

Immunocytochemistry/ Immunofluorescence

1-2 ug/ml

Immunofluorescence

0.5 - 1.0 ug/ml

Immunohistochemistry-Paraffin

0.5 - 1.0 ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
Please Note: Optimal dilutions of this antibody should be experimentally determined.
