title: On the heterogeneity of B40.
abstract: Evidence is presented for the heterogeneity of HLA-B40. At least two sub-groups can be recognized: Bw40.1 which is Cw3 associated and Bw40.2 which is Cw2 associated in Caucasians, but not in other populations. The recognition of Bw41 (Sabell), Bw47 (407*), and Bw48 (KSO) with both local Bw40 antisera and sera from the 7th Histocompatibility Workshop is discussed.
