title: Possible evidence for a new C-locus specificity: studies of the serum Pullium.
abstract: We have presented data from our own experience and from the first serum exchange of the HLA Workshop of the Americas that indicate the serum Pul may identify a new low-frequency specificity of the C locus. One informative family has been studied, and the results are consistant with a C-locus inheritance pattern. No correlation was found with antisera that identify known antigens of the A, B, or C locus. One additional serum, also available for study, seems to react with the same specificity as the serum Pul.
