MACH 3 Mouse HRP-Polymer Detection is a two-step, micro-polymer detection system that provides excellent specificity and sensitivity for mouse primary antibodies. This novel biotin-free kit uses a specific probe to detect mouse monoclonal antibodies followed by a horseradish-peroxidase (HRP) labeled micro-polymer that binds to the probe. The innovative micro-polymer technology increases staining sensitivity 5 to 10 times when compared to conventional dextran polymer HRP detection kits, such as Envision +. It can be used manually and on automated stainers. The kit consists of MACH 3 Mouse Probe and Mouse Micro-polymer HRP.
