Soybean agglutinin (SBA) is a plant lectin, a glycoprotein of nonimmune origin that binds specifically to cell surface carbohydratesthrough noncovalent combinations and thus provokes agglutination of the bound cells. SBA has been used, therefore, to fractionatea variety of cell types. SBA binds approx 60-90% of bone marrow mononuclear cells, including mature myeloid, erythroid, andlymphoid cells, but has very low binding affinity and no toxic effect to the human hematopoietic progenitor cells. In addition,it binds very effectively to certain tumor cells, including neuroblastoma, breast cancer, and Burkitt’s lymphoma cells. Basedon these characteristics, SBA has multiple potential applications for clinical bone marrow, transplantation (BMT)
