concanavalin A

con·ca·nav·a·lin A (conA, con A),

(kon'kă-nav'ă-lin),
A phytomitogen, extracted from the jack bean (Canavalia ensiformis) that agglutinates the blood of mammals and reacts with glucosans; like other phytohemagglutinins, conA stimulates T lymphocytes more vigorously than it does B lymphocytes.

concanavalin A

/con·ca·nav·a·lin A/ (kon″kah-nav″ah-lin) a phytohemagglutinin isolated from the jack bean (Canavalia ensiformis); it is a hemagglutinin that agglutinates blood erythrocytes and a mitogen stimulating predominantly T cells.

concanavalin A

(kŏn′kə-năv′ə-lĭn)
n.
A lectin extracted from the jack bean that acts as a hemagglutinin and mitogen and induces proliferation of T cells.

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.

con·ca·nav·a·lin A

(con A) (kon-kă-nav'ă-lin)
A phytomitogen, extracted from the jack bean (Canavalia ensiformis), which agglutinates the blood of mammals and reactswith glucosans; like other phytohemagglutinins, conA stimulates T lymphocytes more vigorously than it does B lymphocytes.

con·ca·nav·a·lin A

(con A) (kon-kă-nav'ă-lin)
A phytomitogen, extracted from the jack bean (Canavalia ensiformis), which agglutinates the blood of mammals and reacts with glucosans.

concanavalin A (kon´kənav´əlin),

n a hemagglutinin, isolated from the meal of the jack bean, that reacts with polyglucosans in the blood of mammals, causing agglutination. It has been used to stimulate T-cell production.

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.
