Which lectins react with, or agglutinate human blood cells?
Surprisingly few lectins are blood type specific and even fewer of those that are blood type specific are found in foods we eat. The vast majority of lectins in foods agglutinate all or none of the ABO blood types. Wheat germ agglutinin (wheat germ lectin) for instance, will agglutinate all human and animal red blood cells. It is not specific to only one ABO type. Soybean lectin is the same, and it agglutinates all human ABO blood types and several animal species blood as well. Lectins attach to antigens in the gut, primarily in the small intestine, and does occur throughout the entire digestive system. However, the vast majority of lectins are NOT ABO specific.
