     Analysis Note
     Agglutination activity is expressed in μg/mL and is determined from serial dilutions of a 1 mg/mL solution. This activity is the

     lowest concentration to agglutinate a 2% suspension of human erythrocytes in phosphate buffered saline, pH 6.8, after 1 hr 

     incubation at 25 °C.

     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.
