{"Purpose":"<p>\r\n\tThe characterisation of of main leukocyte subsets in peripheral blood cells from mice by flow cytometry.</p>\r\n<p>\r\n\tReliable values of frequencies of leukocyte clusters are very much dependent on the appropriate preparation, acquisition and gating of leukocytes. This method<br />\r\n\tinvolves ammonium chloride erythrocyte lyses, thus preventing interference by larger amounts of erythrocytes. For all stainings, a monoclonal antibody to the<br />\r\n\tcell surface glycoprotein CD45 is used to be able to create a CD45+ gate, allowing discrimination of leukocytes from debris, erythrocytes and thrombocytes. Furthermore, staining with propidium iodide (PI) gates out dead cells. Samples are acquired until a number of 30000 living CD45+ cells is reached for each sample (ref Adler and Busch 2007, submitted). Data are compensated analysed and using FlowJo software.</p>\r\n<p>\r\n\tThis protocol is part of the EMPReSSslim pipeline and is carried out on a cohort of 10 males and 10 females (age matched) at a time.</p>\r\n"}
