Soybean lectin (SBL), a glycoprotein found in seeds, is capable of agglutinating red blood cells. SBL has a molecular weight of 120,000 daltons and is composed of four subunits of 30,000 daltons (Lis and Sharon, 1973). SBL protein comprises 0.5-5% of the total protein in defatted meal, depending upon the soybean variety used (Pull et al., 1978) .
