Phytohaemagglutinin (CAS NO.9008-97-3) has a number of physiological effects and is used in medical research. In high doses it is a toxin.
1.Phytohaemagglutinin (CAS NO.9008-97-3) has a number of effects on cell metabolism: it induces mitosis, and affects the cell membrane in regard to transport and permeability to proteins. It agglutinates most mammalian red blood cell types.
2.As a toxin Phytohaemagglutinin (CAS NO.9008-97-3) can cause poisoning in monogastric animals, such as humans, through the consumption of raw or improperly prepared kidney beans.
3. Medically Phytohaemagglutinin (CAS NO.9008-97-3) is used as a mitogen to trigger cell division in T-lymphocytes, and to activate latent HIV-1 from human peripheral lymphocytes. PHA-L is used by neuroscientists to trace the path of efferent axons of neurons. This usage is called the anterograde labeling method.
Lymphocytes cultured with Phytohaemagglutinin can be used for karyotype analysis.

Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants, especially beans.PHA actually consists of two closely related proteins, called Leucoagglutinin (PHA-L) and PHA-E.It is found in the highest concentrations in uncooked red kidney beans and white kidney beans (also known as cannellini), and it is also found in lower quantities in many other types of green beans and other common beans (Phaseolus vulgaris), as well as broad beans (Vicia faba) such as fava beans.

An experimental teratogen. Experimental reproductive effects. Mutation data reported.

Poisoning can be induced from as few as five raw beans and symptoms occur within three hours, beginning with nausea then vomiting which can be severe and sustained (profuse), then diarrhea. Recovery occurs within four or five hours of onset, usually without the need for any medical intervention.
