Descriptions
Analysis Note Agglutination activity is expressed in μg/ml and is determined from serialdilutions of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a
suspension of 2% human erythrocytes in phosphate buffered saline, pH 6.8 after 1 hr
incubation at 25C. Mitogenic activity is determined by BrdU incorporation in HeLa cell
cultures.
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.3 PHA-P is the protein form of PHA prior to separation and purification
of erythroagglutinin and leucoagglutinin.4 PHA-M is the mucoprotein form.4 Conjugates
are prepared from the corresponding purified lectins.
