Abstract

We show here that the leukemic blast cells from three patients of a total of 15 subsequently diagnosed as having acute leukemia express on their surface the major red cell sialoglycoprotein, glycophorin A (GP‐A). This was demonstrated (1) by indirect immunofluorescence using rabbit anti GP‐A antiserum and (2) by immune precipitation of GP‐A from surface radiolabelled leukemic cells. Since GP‐A is exclusively present on erythroid cells and their precursors, these findings indicate that a higher proportion of the blast leukemias than previously recognized show features of early erythroid differentiation.

## Abstract The spectrum of reactivity with various types of cells of a monoclonal antibody (CH‐4) which detects a private MHC antigen of chickens was analysed. CH‐4 agglutinates only RBCs that possess the __B__^2^ (MHC) haplotype. A new rosetteforming cell (RFC) assay was devised to detect individ
