concanavalin A
[kon′kənav′əlin]
a protein isolated from the jack bean that reacts with polyglucosans in the blood of mammals and causes blood cells to agglutinate. It has been used in immunology to stimulate T cell production.
concanavalin A (kon´k

concanavalin
either of two phytohemagglutinins isolated along with canavalin from the meal of the jack bean (Canavalia ensiformis and other species of Canavalia), which agglutinate the blood of mammals as a result of reaction with polyglucosans.
concanavalin A
binds to sugar residues on cell surfaces and stimulates T lymphocytes to proliferate; has also been shown to inhibit the growth of ascites tumors. Called also Con A.
