Lens culinaris agglutinin (LCA) recognizes sequences containing α-linked mannose residues but recognizes additional sugars as part of the receptor structure, giving it a narrower specificity than Con A. An α-linked fucose residue attached to the N-acetylchitobiose portion of the core oligosaccharide significantly enhances affinity. By exploiting this increased specificity, glycoproteins and glycopeptides can be subfractionated with LCA after initial isolation with Con A.
DyLight™ 649 labeled LCA has an appropriate number of bound fluorochromes, which provides the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes.
Lens Culinaris Agglutinin (LCA), DyLight™ 649 is provided in a 1 mL aliquot at a concentration of 1 mg active conjugate/ml.

Lens culinaris agglutinin is composed of four subunits – two of about 17 kDa and two of 8 kDa.
LCA has been found to be one of the most effective agents in preventing skin allograft rejection in model systems. LCA has been used to purify numerous glycoproteins, including immunoglobulins, histocompatibility antigens, and α2-macroglobulin.
Accompanying each fluorescent lectin is an analysis data sheet summarizing the results of our quality control tests and providing pertinent information on the product. All of these reagents are supplied as solutions preserved with sodium azide.
