Phytohemagglutinin (PHA-M) is a lectin extracted from
red kidney bean Phaseolus vulgaris. PHA-M is the most
common mitogen used for the stimulation of cell division
in lymphocyte cultures. PHA-M is a mucoprotein
consisting of two subunits, a leucoagglutinin (PHA-L)
and an erythroagglutinin (PHA-E). Leucoagglutinin is
responsible for mitogenic property of PHA-M as it has
high affinity for lymphocyte surface receptors.
TCL071 is a sterile filtered solution of 1mg per ml PHAM in sterile tissue culture water.
