Multiple Antigen Labeling Simplified

A key advantage of the ImmPRESS® Polymer Reagent is that it significantly shortens staining times for multiplex immunohistochemistry (IHC) protocols.

  • Fewer steps than conventional protocols decreases slide handling.
  • Eliminates the need for avidin/biotin blocking steps in samples with endogenous biotin.
