A phytomitogen from plants that agglutinates red blood cells.

The term is commonly used specifically for the lectin obtained from the red kidney bean (Phaseolus vulgaris) which is also a mitogen that stimulates T lymphocytes more vigorously than B lymphocytes.

Some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture.

They bind to oligosaccharide containing N acetyl galactosyl residues.

Synonyms: phytolectin.

American spelling: phytohemagglutinin
