Leukocyte Grouping. A Method and Its Application*

Leucocyte and Platelet Groups and their Practical Significance

“…Their presence on leucocytes and/or platelets does not exclude their simultaneous presence in the tissues, and some have been demon strated by absorption tests in the liver, kidneys and placenta, and in the lymph nodes [32, 110,82]. a) Antigens found only on platelets.…”

Hl‐a Antigens on Kidney Cells and the Use of Kidney Cells as a Target in the Detection of Donor Specific Cytotoxic Antibodies in Renal Transplantation

“…HL-A antigen.s have been denion.strated on renal tissue by absorption {van Rood, 1962;Rerah, Hors and Daiisset, 1970), although it has been suggested bv Berah et al (1970) that there is a (Quantitative difference in the amount of HL-A antigen in difFerent tissues. Their studies indicated that there was less of the HL-A antigen that they studied {HL-A2) per unit wet weight of kidney tissue than on an e(]uivalent weight of lymphocytes.…”

Leucocyte and Tissue Groups^1

“…Extending their studies systematically, van Rood et al [13,19,20,21] have described two other pairs of antithetical antigens 5a5b and 6a6b. 5a and 5b are present in 33% and 97% respectively of the population of Holland, and Lalezari [12] has recently studied a further example of the antibody anti-5b.…”

“…In the same year van Rood, in his outstanding Thesis [18], was the first to describe a system with two alleles, the 4a4b system. He used a statistical technique, involving the use of two by two comparisons on an electronic computer of the reactions of two sera.…”
