Now everyone can characterize cellular signaling mechanisms and better understand the complexity of multiple signaling pathways. Because PerkinElmer now offers the flexibility and efficiency of performing cellular label-free assays in either a 96-well or 384-well format, your throughput and liquid handling is no longer a barrier to the benefits of phenotypic analysis. If you are interested in label-free, but would like to develop your assay in a 96-well format to improve cost efficiencies to do manual liquid handling or use a lower throughput than 384 wells, PerkinElmers new 96-well cellular label-free assay plates are the perfect solution. The sensitivity of the EnSpire label-free platform enables the detection of cellular responses from endogenously and recombinantly expressed receptors, as well as subconfluent cells, enables scientists to work with fewer cells and also suggests its applicability for use with primary cells and stem cell where cell numbers can be limited.
