NCIt definition : A class of lectins, found in beans, with hemagglutination properties. Phytohemagglutinin
binds to complex oligosaccharides containing galactose, N-acetylglucosamine and mannose,
causing agglutination of most mammalian red blood cell types. It induces mitosis and
affects cell membrane permeability, thereby facilitating protein transport.;
Alternative definition : NCI-GLOSS: A substance found in plants that causes red blood cells to clump together
and certain white blood cells to divide.;
