Related Product Information for Vicia villosa Lectin lectin
This lectin is a family of tetrameric glycoproteins consisting of combinations of A and B subunits similar in structure to PHA and GSL I. The dominant isolectins in our preparations appear to be B subunit-rich. VVL recognizes preferentially alpha- or beta-linked terminal N-acetylgalactosamine, especially a single alpha N-acetylgalactosamine residue linked to serine or threonine in a polypeptide (the "Tn antigen"). Evidence suggests that this lectin also may require specific amino acid sequences at the receptor site of glycosylation. The disaccharide galactosyl (a-1,3) N-acetylgalactosamine is also a potent inhibitor of this lectin. Agarose bound Vicia Villosa Lectin is prepared from affinity-purified lectin. Heat stable, cross-linked 4% agarose beads with a molecular weight exclusion limit of about 2x10e7 are used as the solid-phase matrix to which the lectin is covalently bound. The attachment of the lectin to the solid phase is carefully controlled in order to preserve the activity of the lectin as well as to minimize conformational changes of the bound lectin which might result in nonspecific ionic or hydrophobic interactions. The technique developed to couple lectins to agarose provides a very hydrophilic spacer arm between the protein and the matrix. This ensures maximum expression of the carbohydrate binding activity of the lectin. The linkage is very stable over a range of pH values and, unlike cyanogen bromide linkages, proteins are not leached off the gel by Tris or other routinely used buffers. In addition, residual charges generated during cyanogen bromide conjugation which can produce nonspecific binding are not present on the gel following our coupling procedure.

Product Notes
The Vicia villosa Lectin (Catalog #AAA656096) is a Lectin and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Vicia villosa Lectin can be used in a range of immunoassay formats including, but not limited to, ELISA (EL/EIA). Suitable for use in ELISA. Researchers should empirically determine the suitability of the Vicia villosa Lectin for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Vicia villosa Lectin, Lectin" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
