The Kinex™ 850-antibody microarray tracks the levels and functional states of many diverse proteins in human and animal cell and tissue specimens and features more than 330 phosphosite and 540 pan-specific antibody probes. This can provide researchers with a proteomics tool to study changes in cell-signaling proteins that occur in response to treatments, drugs, toxins, pathological, and other experimental conditions. The KAM-850 kit covers a range of protein kinase and protein phosphatases targets and their regulatory phosphorylation sites. The Kinex antibody microarray can enable researchers to identify biomarkers for disease diagnostics purposes and for discovery of new research leads.
