EasyCyte Plus microcapillary flow cytometry system provides automated cell count and viability analyses of a chosen population to quality control cells prior to commencement of complex staining procedures, preventing waste of valuable cells and reagents. Complex stained cells are detected using ExpressPro dedicated multi-parametric detection software. The system includes such features as absolute cell counts, 6 parameters (4 fluorescent colors, 2 light scatter), and a blue laser for access to commonly used fluorescent dyes. The 4th color option, combined with the built-in 96-well autosampler, allows researchers to perform complex biological studies such as white blood cell phenotyping, cell signaling, cytokine production, activation marker analysis, and multiplex compound screening. Monitoring the interplay of up to four different biological mechanisms simultaneously improves the efficiency of experimental outputs.  Not only does this shorten the number of iterations for any one experiment, it also comes that much closer to mimicking the complex biological responses within the body.
