Ultivue UltiMapper Reagents

Ultivue has launched its UltiMapper portfolio of reagents for whole-slide protein biomarker spatial detection and analysis in tissue. More specifically, the company's UltiMapper I/O reagent kits are ready to use and enable profiling and characterization of tumor immuno-oncology markers in formalin-fixed, paraffin-embedded samples. Analysis can be conducted using instrumentation and software found in most immunohistochemistry laboratories, Ultivue said. The reagents are powered by Ultivue's InSituPlex technology, which combines DNA-barcoded antibodies with complementary fluorescent DNA barcodes.
