Technical Data
Arachis hypogaea (PNA, Peanut Agglutinin) (Texas Red)
Lectins are derived from the extracts of plants, animals, viruses and microorganisms and are known to agglutinate red blood cells. These agglutinins can select cell types according to blood group activities utilizing sugar-binding mechanisms. Lectins form precipitates with glycoconjugates and are useful for identifying or separating oligosaccharides with identical sugar compositions such as galactose, mannose or glucose.
Arachis hypogaea (PNA, Peanut Agglutinin), 110kD, is composed of four identical subunits of ~27kD each, is galactose-specific, with strong anti-T-antigen activity. T-antigen") is present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. PNA does not agglutinate normal human erythrocytes, but strongly agglutinates neuraminidase-treated red blood cells. The presence of Ca++ can enhance the binding of PNA to receptors. Asialo GM1 ganglioside is also thought to be a major cell surface receptor for PNA. PNA is useful in normal and tumor tissue determination for transitional mucosa malignancies.

Suitable for use in Immunofluorescence, Immunocytochemistry and Immunohistochemistry. Other applications not tested.
