Rat mast cell granules and plasma membrane fractions were obtained by homogenization of highly purified rat mast cells and isolation in a Percoll gradient and a sucrose gradient, respectively. Immunostaining of rat mast cells, granules and plasma membrane fractions was performed with mouse monoclonal antibody M6764 which was produced against the crude membrane fractions of the neural tubes. Rat mast cells and granules were immunostained with the monoclonal antibody, but not the plasma membrane fractions. The granules fixed with glutaraldehyde-paraformaldehyde showed ring-like forms. Chloroform-methanol treatment did not effect the staining of rat mast cells and granules with the monoclonal antibody. Western blotting analysis of rat mast cells and granules with the monoclonal antibody showed broad protein bands ranging from 100 to 250 kD.

UI MeSH Term Description Entries
D008407 Mast Cells Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR. Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured 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.
