• Two grades of purity; PHA-M pure and PHA-M crude
• Potent mitogen
• High erythroagglutinating activity
• Stimulation of cell proliferation in lymphocyte cultures • Erythroagglutination
PHA-M is the mucoprotein variant of phytohemaglutinin isolated from red kidney bean. It contains up to 20% carbohydrates in conjugation with the protein which presents two bands corresponding to about 35 kDa according to SDS-PAGE in presence of mercaptoethanol. It is a potent mitogen used to stimulate cell proliferation in lymphocyte cultures and also has a powerful erythroagglutinating activity.
Storage and stability
Stable for at least 3 years from production date when stored below -20 ̊C. May be shipped at ambient temperature. After reconstitution in PBS pH 7.4, the solution may be stored frozen in working aliquots for up to 12 months. Repeated freez- ing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
