Euonymus europaeus Lectin (EEL) (Biotin)

Cat no: E9000-60A

Euonymus europaeus Lectin (EEL) (Biotin)

This glycoprotein of about 140,000D consists of six closely related lectins with isoelectric points between pH 4.3 to pH 4.7. Most of the 35,000D subunits appear to consist of two disulfide linked chains of about 17,000D. This lectin has a carbohydrate binding specificity toward type 1 or type 2 chain blood group B structures but will bind other oligosaccharides containing galactosyl (a-1,3) galactose. Unlike Ulex europaeus and Lotus tetragonolobus lectins, EEL has a high affinity toward type 1 chain blood group H structures. This lectin has been reported to bind to endothelial cells from human and non-human sources and recognizes carbohydrate structures on the surface of stimulated murine peritoneal lymphoid cells. This biotinylated lectin conjugate is prepared from affinity-purified lectin and is optimally labeled with biotin. Essentially free of inactive lectin conjugate and containing no free biotin, this biotinylated lectin provides an ideal intermediate for examining glycoconjugates using the Biotin-Avidin System. First the biotin-labeled lectin is added, followed by an ABC Reagent, Avidin D conjugate, or streptavidin derivative. Another possible application is in the isolation of lymphokines and other products of mitogenic stimulation.\n\nApplications: \nSuitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nInhibiting/Eluting Sugar: \n500mM lactose\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 6 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.
