Product Description

Medicago AB Products Are Available Worldwide

For Research Use Only

Phaseolus vulgaris lectin E (PHA-E) is a tetrameric protein with a molecular weight of 128 kDa. It is isolated from red kidney beans by affinity chromatography and ion-exchange chromatography. The lectin recognizes terminal galactose residues of complex glycans on mammalian glycoproteins. Because it has high erythrocyte agglutinating activity, it is also known as Erythroagglutinin (PHA-E). PHA-E is not blood group specific. Less than 5 µg/ml will agglutinate human erythrocytes type O.

PHA-E is supplied as a white to light-pink lyophilized powder from 50 mM NH4HCO3.

For laboratory use only.
