Jacalin Coated Surface can be used in assays for binding carbohydrate-binding proteins and glycoproteins.

Jacalin, belonging to the lectins family, is a tetrameric (M.W. 40 kDa) carbohydrate-binding protein isolated from the seeds of jack fruit Artocarpus integrifolia agglutinin. It is well known that lectins have been used extensively for the isolation of glycol-conjugates and glycoproteins with specific carbohydrate structures.

Jacalin shows specific affinity for molecules containing non reducing α-D-galactosyl groups, usually present in the biochemical structure of IgA1 and cell membranes.

Examples of applications for Jacalin Coated surface

  • Human IgA1 specific binding, sterically oriented
  • Purification of human immunoglobulins (especially IgA1)
  • Separation of immunocomplexes antigen-antibody
  • Separation of IgA1 from contaminants
  • Stimulation of T-cells
