phytohemagglutinin

 [fi″to-he″mah-gloo´tĭ-nin]
a lectin isolated from the red kidney bean (Phaseolus vulgaris); it is a hemagglutinin that agglutinates mammalian erythrocytes and a mitogen that stimulates predominantly T lymphocytes. Abbreviated PHA.

phy·to·hem·ag·glu·ti·nin (PHA),

(fī'tō-hēm'ă-glū'ti-nin),
A phytomitogen from plants that agglutinates red blood cells. The term is commonly used specifically to refer to the lectin obtained from the red kidney bean (Phaseolus vulgaris), which is also a mitogen that stimulates T lymphocytes more vigorously than B lymphocytes.
Synonym(s): phytolectin
