Phaseolus vulgaris lectin L (PHA-L) (2 mg)
For Research Use Only
Phaseolus vulgaris lectin L is composed of four units each of molecular weight of 31 kDa. The protein has a molecular weight of 126 kDa. It is isolated from red kidney beans by affinity chromatography.
Also known as Leucoagglutinin (PHA-L), this lectin has high mitogenic and leucoagglutinating activity, but low erythroagglutinating activity. The lectin recognizes terminal galactose residues of complex glycans on mammalian glycoproteins such as thyroglobulin. PHA-L does not agglutinate human erythrocytes at concentrations of 250 µg/ml or less, and is non-specific for blood groups.
Phaseolus vulgaris lectin is supplied as a white lyophilized powder from 10 mM NH4HCO3.For laboratory use only.
