Ulex Europaeus Lectin 1 (UEA 1, UEA1, UEA I, UEA-I, Anti-H(O) Lectin 1, Anti-H(O) Lectin I, Ulex europaeus Agglutinin)

Lectins are highly specific carbohydrate binding proteins useful in carbohydrate and cell membrane studies, as well as cell agglutination and typing techniques. Anti-Ulex Europaeus-I (UEA-I) Lectin is developed in rabbit using purified Ulex Europaeus-I lectin from gorse seeds as the immunogen. Anti-UEA-I Lectin is specific for UEA-I bound to vascular endothelium and squamous epithelium of human tonsil by indirect immunofluorescent staining. While erythrocytes may be stained,no other tonsilar elements are reactive with the antibody. Anti-UEA-I reacts with UEA-I bound to human endothelial cells of normal and neoplastic blood and lymphatic vessels. It also reacts with human epithelia such as in the colon, bronchus, epidermis, sweat gland ducts and hair follicles. Epithelia from other species may also react with the antibody. Anti-Ulex Europaeus-I Lectin may be used for studies of vascular structures in formalin-fixed, paraffin-embedded tissue or frozen tissue preparations. The antibody may be useful in the detection of vascular tumors, the investigation of vascular invasion by tumor cells, for determination of UEA-I binding to normal, embryonal, dysplastic and neoplastic epithelia, and the study of storage diseases such as fucosidosis Ulex Europaeus-I Lectin is a 46kD glycoprotein known to interact with alpha-L fucosyl residues in oligosaccharides present on the membranes of human blood group O erythrocytes, human endothelial cells and a variety of human and animal epithelial cells. Applications: Suitable for use in Immunofluorescence and Immunohistochemistry (Fr) (paraffin-embedded sections). Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Positive Control: Human tissue Cellular Localization: Cytoplasmic (probable) Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degrees C. Aliquots are stable for at least 3 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
