Leu Antigens 27 Aug 2013 | 01:46 pm
Antigens expressed primarily on the membranes of living cells during sequential stages of maturation and differentiation. As immunologic markers they have high organ and tissue specificity and are use...
Leu-11 Antigens 27 Aug 2013 | 01:46 am
Specific molecular sites on the surface of various cells, including B-lymphocytes and macrophages, that combine with IMMUNOGLOBULIN Gs. Three subclasses exist: Fc gamma RI (the CD64 antigen, a low aff...
Leu-19 Antigen 26 Aug 2013 | 01:46 pm
The 140-kD isoform of NCAM (neural cell adhesion molecule) containing a transmembrane domain and short cytoplasmic tail. It is expressed by all lymphocytes mediating non-MHC restricted cytotoxicity an...
Leu-2 Antigens 26 Aug 2013 | 01:46 am
Differentiation antigens found on thymocytes and on cytotoxic and suppressor T-lymphocytes. CD8 antigens are members of the immunoglobulin supergene family and are associative recognition elements in ...
Leu-7 Antigen 25 Aug 2013 | 01:46 pm
Oligosaccharide antigenic determinants found principally on NK cells and T-cells. Their role in the immune response is poorly understood.

Leukemia, Common Acute Lymphoblastic Antigens 24 Aug 2013 | 01:46 pm
Enzyme that is a major constituent of kidney brush-border membranes and is also present to a lesser degree in the brain and other tissues. It preferentially catalyzes cleavage at the amino group of hy...
Leukocyte Antigens 24 Aug 2013 | 01:46 am
Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine ...
Leukocyte Common Antigen 23 Aug 2013 | 01:46 pm
High-molecular weight glycoproteins uniquely expressed on the surface of all leukocytes and their hemopoietic progenitors. The CD45 family consists of multiple members that are all products of a singl...
Leukotriene Antagonists 23 Aug 2013 | 01:46 am
