Changes in cell surface antigen expression during hemopoietic differentiation.
Human bone marrow cells were separated on a fluorescence activated cell sorter (FACS) according to their binding of a series of monoclonal antibodies; the positive and negative fractions were cloned for erythroid burst and colony-forming units (BFU-E and CFU-E) and myeloid colony-forming units (CFU-GM), and cytocentrifuge slides were prepared for microscopy of maturing precursors. The pattern o...
متن کاملEXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...
متن کاملA novel cell surface antigen, immature thymocyte antigen-1, is involved in the differentiation of murine thymocytes.
A mAb, 1-23, which recognizes a novel cell surface Ag on immature murine thymocytes (designated as IMT-1 for immature thymocyte antigen-1) was prepared. IMT-1 was found to be expressed on 40 to 50% of CD4-8- double negative (DN), 5 to 10% of CD4-8+, and 5 to 20% of CD4+8+ double positive (DP) thymocytes in adult mice, but not expressed on CD4+8- thymocytes or peripheral T lymphocytes. It was no...
متن کاملChanges in cell surface antigen expressions during proliferation and differentiation of human erythroid progenitors.
Cell surface antigen expression during proliferation and differentiation of human erythroid progenitors was examined using a combination of sequential micromanipulations of paired daughter cells derived from erythroid burst-forming units (BFU-E) and immuno-staining with a panel of monoclonal antibodies. Single hematopoietic progenitors were identified in methylcellulose cultures containing huma...
