[RX] MicroStacker™ Mouse-on-Mouse HRP Polymer

A biotin-free HRP polymer detection system designed for the reliable detection of mouse primary antibodies on mouse tissue sections.

No Blocking Required

Specially engineered anti-mouse secondary antibodies reduce interference from endogenous mouse IgG, eliminating the need for an additional mouse IgG blocking step and simplifying the staining workflow.

Low Background and High Specificity

The biotin-free design avoids background staining caused by endogenous biotin. Fab’ fragments are used instead of whole IgG secondary antibodies to reduce non-specific binding to endogenous Fc receptors, delivering cleaner and more specific staining.

Enhanced Sensitivity

MicroStacker™ technology enables orientation-controlled attachment of Fab’ fragments to a compact poly-HRP core. This helps preserve antibody binding activity during conjugation and enhances signal intensity.

Consistent Staining Performance

The compact micro-polymer structure supports effective penetration into tissue sections and reliable detection of nuclear, cytoplasmic, and membranous antigens.

Superior Polymer Design

Compared with conventional Mouse-on-Mouse methods and bulky dextran-based HRP polymers, MicroStacker™ provides a simpler workflow, lower background, and sensitive, reproducible staining results.
