Application

Concanavalin A from Canavalia ensiformis (jack bean) has been used:
  • to induce spleen blastogenesis
  • to generate ConA blast targets from B6 and lpr spleen cells
  • to stimulate splenic lymphocytes from estrogen-and placebo-treated mice

Biochem/physiol Actions

Con A is not blood group specific but has an affinity for terminal α-D-mannosyl and α-D-glucosyl residues. Ca2+ and Mn2+ ions are required for activity. Con A dissociates into dimers at pH 5.6 or below. Between pH 5.8 and pH 7.0, Con A exists as a tetramer; above pH 7.0 higher aggregates are formed. Con A exhibits mitogenic activity which is dependent on its degree of aggregation. Succinylation results in an active dimeric form which remains a dimer above pH 5.6.

Analysis Note

Where reported, agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, containing Ca2+ and Mn2+ of a 1 mg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C.
