A simpler method for combined detection of human peripheral lymphocyte subpopulations. 1979

Y Lee, and Y Yoshizawa, and R G Carr, and M M Yokoyama

A method for the simultaneous enumeration of human lymphocyte subpopulations was developed by mixing lymphocytes, sheep red blood cells and immunobeads. Thymus-dependent lymphocytes (T cells) are detected by rosette formation with AET-treated sheep blood cells, and thymus-independent lymphocytes (B cells) are identified by rosette formation with polyacrylamide gel coated with antibody specific to both light chains (chi and lambda) of immunoglobulin. The major advantage of this technique is that it is simple, convenient and reproducible. This method also detects lymphocytes possessing both T and B cell markers (double-marker lymphocytes). Three different types of rosettes are distinquishable under light-microscopic observation, and this method may be valuable in clinical use.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000918	Antibody Specificity	The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.	Antibody Specificities,Specificities, Antibody,Specificity, Antibody
D012397	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.	Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
