title: B lymphocyte alloantigen specificities present on cultured lymphoblastoid cell lines.
abstract: Thirty-three of 34 cultured human lymphoblastoid B cell lines have been shown to express four out of five polymorphic non-HLA specificities expressed by normal B lymphocytes. The specificities were detected by 32 alloantisera produced by absorption with pooled platelets to remove HLA activity and selected from over 400 pregnancy sera. One B group (B2) which was expressed by 23% of a panel of normal B lymphocytes was not found on any of the cultured lines tested. Four T cell lines tested and myeloid line (K562) did not react with any of the B cell alloantisera.
