Karl Landstiener was the first to demonstrate the existence of different blood group antigens in 1900. We now recognize 29 different blood group systems comprising over 250 antigens, but the most well known are the ABO (also known as ABH) and rhesus (Rh) systems.

Relatively stable proteins isolated from human heart and from human and rhesus monkey skeletal muscles, are capable of binding to /3-D-galactosides. Gel precipitation and radioimmunoassay studies with rabbit antiserum to calf heart lectin revealed antigenic cross-reactions between the primate and bovine muscle lectins. The lectin from calf heart shows a greater specificity towards the terminal disaccharide (lactosamine) units of blood-group antigen precursor chains than does the Ricinus communis lectin.

In 1930, Karl Landsteiner received the Nobel Prize for medicine in his discovery of the four major blood groups, which he had initially discovered in 1901. In 1927, he identified the M and N groups, and in 1940, he discovered the Rhesus (Rh) factor. 

Comparative studies of the blood-group A substances of invertebrates have been reported, and the results of an examination of tissues from pigs, horses, baboons. Rhesus monkeys, and humans are consistent with, but do not unequivocally confirm, the microheterogeneity of glycoproteins exhibiting blood-group activity. ...

In another study by Casanova et al. (1988), blood levels of formaldehyde were determined in Rhesus monkeys after exposure to 6 ppm formaldehyde for 6 hours/day, 5 days/week for 4 weeks. Immediately after the last exposure, tlie monkeys were sedated and blood samples were collected within 7 minutes and at 45 hours after exposure. Blood samples were analyzed for fonnaldehyde content by gas chromatography/mass spectrometry (GC/MS). Mean blood concentrations at 7 minutes and 45 hours postexposure were 1.84 and 2.04 g/g, respectively. Blood concentrations of formaldehyde in the three nonexposed monkeys (2.42 g/g) were not significantly different from those of the exposed group. Tlie authors concluded that exposure to moderately high levels of formaldehyde had no effect on blood concentrations due to rapid local metabolism.
