| E rosette | The adherence of erythrocytes to cells. Sheep erythrocytes will adhere spontaneously to human T-cells, forming rosettes. (05 Mar 2000) |
|---|---|
| E rosettes | <haematology> The clustering of sheep erythrocytes around a leucocyte or other cell. E rosette formation is used as a marker for T lymphocytes of humans and most mammals, in this case erythrocytes are untreated, compared with other rosette tests such as EA where erythrocytes have antibody bound to their surface. (06 Mar 1998) |
| rosette | <dermatology> A group of organs or other body features, such as leaves or hair, which are clustered and crowned around a common point of attachment. (09 Oct 1997) |
|---|---|
| rosette formation | The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing fc receptors. Rosette formation can be used to identify specific populations of these cells. (12 Dec 1998) |
| rosette-forming cells | T lymphocytes with an affinity for sheep erythrocytes and which, when suspended in serum, bind the uncoated, nonsensitised erythrocytes in a rosette formation. (05 Mar 2000) |
| rosette test | A test for rosette-forming cells (T-lymphocytes) in which these cells and sheep erythrocytes, are incubated and centrifuged lightly, then examined under a microscope for rosette formation or adherence of erythrocytes to T lymphocytes. (05 Mar 2000) |
| chromosome rosette | Right before metaphase, human chromosomes briefly form this single ring structure. (09 Oct 1997) |
| chromosome rosette john jordan | Right before metaphase, human chromosomes briefly form this single ring structure. (09 Oct 1997) |
| EAC rosette | <haematology> Rosettes formed from erythrocytes (E) coated with antibody (A) and complement (C). A test for C3b or C3bi receptors (CR1 or CR3). The rosettes form more easily then E or EA rosettes. See: E rosettes. (16 Mar 2000) |
| EAC rosette assay | <haematology> Rosettes formed from erythrocytes (E) coated with antibody (A) and complement (C). A test for C3b or C3bi receptors (CR1 or CR3). The rosettes form more easily then E or EA rosettes. See: E rosettes. (16 Mar 2000) |
| EA rosette | A test for the presence of Fc receptors. (18 Nov 1997) |
| E-rosette test | A test to identify T lymphocytes by mixing purified blood lymphocytes with serum and sheep erythrocytes; rosettes of erythrocytes form around human T lymphocytes on incubation. (05 Mar 2000) |
| E rosette test |
A laboratory test performed to identify human T lymphocytes. When T lymphocytes combine with sheep red blood cells in a culture, a cluster of cells called a rosette forms. This test is often replaced by the use of monoclonal antib

| E rosette a. |
an assay for human T lymphocytes based on the existence of a specific receptor on T cells for a sheep red blood cell membrane antigen. Peripheral blood lymphocytes are incubated with sheep red cells. T cells are surrounded by a ring of erythrocytes (an E rosette) and are counted using a hemacytometer.
