ImmPRESS™ One-Step Polymer Systems

ImmPRESS™ Polymer Detection Systems

ImmPRESS™ Polymer Reagents consist of unique micropolymers of highly active peroxidase or alkaline phosphatase enzyme attached to highly cross-adsorbed, affinitypurified secondary antibodies. This micropolymer conjugation technology allows a higher density of enzymes per antibody to bind to the target with minimal steric interference. The ImmPRESS™ Polymer Reagents produce outstanding immunohistochemistry and immunocytochemistry results due to increased target accessibility, binding specificity, and signal intensity along with low background staining.

  • High sensitivity and very low background for crisp, strong staining
  • Ready-to-use, one-step detection system – no mixing or titering
  • Includes prediluted blocking serum
  • Shorter assay time
  • Non-biotin based
  • Excellent resolution
  • Especially suited for nuclear and membrane antigens
  • Ideal for multiple antigen labeling (p. 30-33)

ImmPRESS™ VR Polymer Kits

ImmPRESS™ VR (Veterinary Reagents) Kits are available additionally cross-adsorbed to ensure minimal cross-reactivity against endogenous tissue elements in animal species commonly used for diagnostics and research-based animal models (bovine, goat, sheep, swine, horse, cat, dog, rabbit, rat, mouse).

Using the ImmPRESS™ Polymer Kits

1 Add Primary Antibody
2 Add ImmPRESS™ Reagent
3 Add Enzyme Substrate
