What does Dolichos biflorus aggluntinate?
A1 or A1B cells
What does Bandeiraea simplicifolia agglutinate?
B cells
What does Ulex eurpoaeus agglutinate?
O cells/H-antigen (anti-H)
ABO antigens can be detected on red cells of embryos as early as:
5 to 6 weeks of gestation
adult levels of ABO antigens are generally observed by age
2 - 4 y/o
FUT1
H gene
FUT# that specifically fucosylates type 2 chain oligosaccharides on red cell glycoproteins and glycolipids to form type 2 chain H
FUT1
FUT2
Secretor gene
FUT# that recognizes type 1 chain precursors to form type 1 chain H and Leb antigens
FUT2
FUT3
Lewis gene
