General description
Phytohemagglutinin (PHA), the lectin extract from the red kidney bean. PHA consists of five isolectins (L4E0, L3E1, L2E2, L1E3, L0E4) each being a tetramer held together by noncovalent forces. The subunits L (leukocyte reactive) have a high affinity for lymphocyte surface receptors, but little for those of erythrocytes, and are responsible for the mitogenic properties of the isolectins. E (erythrocyte reactive) is responsible for the erythrocyte-agglutinating properties.
Application
Phytohemagglutinin (PHA) is a potent mitogen used to stimulate cell proliferation in lymphocyte cultures.
Phytohemagglutinin-M (PHA-M) has been used in the activation of Jurkat and primary cells. It has also been used to treat polymorphonuclear blood cells(PMBCs)
Biochem/physiol Actions
Phytohemagglutinin (PHA) has mitogenic and potent cell agglutinating activities. It binds to T-cell membranes and stimulates cell division and metabolic activity. PHA has the ability to stimulate close contacts between cell membranes.
Specifications
Biological activity: <10 μg/ml for maximal stimulation of DNA synthesis (BrdU incorporation) with human peripheral blood lymphocytes.
Preparation Note
Working concentration: 2 - 10 μg/ml
Approximately 2 - 10 μg/ml for the stimulation of peripheral blood lymphocytes
Storage conditions (working solution): The reconstituted solution is stable for 2 weeks at 2 to 8 °C or for several months when stored in aliquots at -15 to -25 °C.
