This study demonstrates the suitability of microfluidic structures for high throughput blood cell analysis. The microfluidic chips exploit fully integrated hydrodynamic focusing based on two different concepts: Two-stage cascade focusing and spin focusing (vortex) principle. The sample--A suspension of micro particles or blood cells--is injected into a(More)
A surface-labeled lyophilized lymphocyte (sLL) preparation has been developed using human peripheral blood mononuclear cells prelabeled with a fluorescein isothiocyanate conjugated anti-CD4 monoclonal antibody. The sLL preparation is intended to be used as a reference material for CD4+ cell counting including the development of higher order reference(More)
Reference measurement procedures are indispensable to reliably determine blood cell concentrations, since medical diagnosis, initiation of therapy and control of blood products are often based on concentration limits of specific cell subpopulations. We have developed a reference procedure to directly determine stem cell concentrations. In the same(More)
