Product Features:

- 2nd generation of polymer HRP (non-biotin) system

- More sensitive than Polink-1 HRP system with clean background

- 2-step polymer detection system

- Compatible with either manual or automated systems

- Better results on difficult-to-work antibodies and nuclear staining

- Save cost due to further dilution of primary antibodies

Polink-2 HRP detection kit is the second generation of polymer-based detection system that

uses proprietary polymer helper and polymeric HRP-linked secondary antibody conjugates to achieve

super sensitivity and consistent immunostaining.  

This technology provides excellent sensitivity and high specificity.  It is about 3-4 times more

sensitive than the 1-step polymer detection system and biotin-streptavidin system.   It helps to

achieve better results on difficult-to-work antibody and nuclear staining.  It is a biotin-free system, 

so therefore overcomes the non-specific staining caused by streptavidin/biotin system due to

endogenous biotin.  Since it has higher sensitivity than other conventional methods and the 1-step

polymer detection system (Polink-1 HRP system), users may need to further dilute the concentration

of primary antibodies if switching from conventional three-step or Polink-1 HRP detection methods.  

Refer to GBI catalog page 14 to choose Polink-2 HRP for DAB or Polink-2 HRP for AEC.  For single

species capacity or ultra sensitivity, please choose the third generation of polymer detection system,

Polink-2 Plus HRP detection system, on catalog page 16-19.
