[Study of lymphocyte subpopulations using peanut, soybean and snail lectins]

The method of penning in plastic dishes was to isolate the PNA+ and PNA- cell populations from the tonsil tissue. Carbohydrate determinants of lymphoid cell surface membranes being at varying stages of antigen-independent and antigen-dependent differentiation have been studied with the use of peanut, soya and edible snail lectins conjugated with horse radish peroxidase.
