Protein profile and stimulation potential of partially purified lectins from two varieties of Phaseolus vulgaris L.

Phytohaemagglutinin obtained from P. vulgaris is a commonly used mitogen in lymphocyte cultures. The mitogenic potential of different cultivars of P. vulgaris vary. The present investigation encompasses the characterization of partially purified lectins from two varieties of P. vulgaris on the basis of their protein profile, lymphocyte transformation test by light and scanning electron microscopy and incorporation of radioactive thymidine.
