Sugar specificity: N-Acetylgalactosamine (GalNAc)

Additional specificity details: D-GalNAc

Structure: Tetrameric lectin composed of four identical subunits of 30 kDa

SBA has specificity for blood groups A1, A2 and B. The lectin interacts better with neuramidase-treated cells than with untreated cells. It has selective affinity for lymphocytes and human CD34+ hematopoietic stem cells. Immobilized conjugates of SBA are therefore important tools for removing T-cells in bone marrow transplantation.

Synonyms:Soy bean agglutini (SBA)

Laboratory reagent for research and development only. Not for human or animal use.
