Application

Lectin from Phaseolus vulgaris (red kidney bean) has been used:
  • for the stimulation of cluster of differentiation (CD4+) T cells
  • for the activation of primary peripheral blood lymphocytes
  • for the stimulation of peripheral blood mononuclear cells

Biochem/physiol Actions

PHA consists of two molecular species, an erythroagglutinin (PHA-E) which has low mitogenic activity and high erythroagglutinin activity, and leucoagglutinin (PHA-L) which has high mitogenic and leucoagglutinating activity, but very low erythroagglutinating activity.
PHA-E is not blood group specific, but agglutination can be inhibited by certain oligosaccharides. PHA-P is the protein form of PHA prior to separation and purification of erythroagglutinin and leucoagglutinin. PHA-M is the mucoprotein form. Conjugates are prepared from the corresponding purified lectins.
