Glycine max agglutinin (SBA) is isolated is purified by affinity chromatography. It is consists of four subunits of identical size. SBA has specificity for blood groups A1, A2, and B, and interacts better with neuramidase-treated cells than untreated cells. This lectin has selective affinity for lymphocytes and human CD34+ hematopoietic stem cells. Immobilized conjugates of SBA are important tools for removing T-cells in bone marrow transplants.Some lectin trigger mitogenic activities in differentiated or resting cells. These lectins do not cause toxicity. A right concentration of affinity purified Glycine max (Soybean) Lectin (SBA) is provided in a sterile solution for stimulating cells that respond to the lectin.
