Antigen Report: HLA-Cw2
Six alloantisera contained anti-Cw2: 9w455–9w460. In the combined analysis, serum 9w458 had the lowest number of extra reactions and the fewest false negatives, whereas the other sera tended to give some extra reactions, usually associated with Cw7, B27, and/or B7. In our experience, sera 9w457, 9w458, and 9w460 behaved perfectly well as anti-Cw2 reagents, while 9w455, 9w456, and 9w459 were difficult to read because of turbidity. There was no evidence that Cw2 may be split.
