Navinci - Reinventing Immunostaining and in situ proximity ligation

Navinci Logo

The Naveni technology offers the possibility to study proteins and their interactions in situ at the molecular level, while maintaining the spatial resolution and integrity of the tissue microenvironment.

Navinci’s researchers are the developpers of the Duolink® technology. With the Naveni technology, they bring the next generation technology to the market.

PLA staining

Assay principle

Navinci NaveniFlex Workflow of PLA

After the incubation with the primary antibody, the sample is incubated with the Navenibodies which function as a secondary antibody. If the Navenibody pairs are in close proximity, they become activated (digestion) and the circle creation is initiated. Once completed the signal is amplified by rolling circle amplification. The resulting fluorescent signal can be read out using a fluorescent microscope and quanitified with most image analysis softwares.

Key Advantages

10x increase in sensitivity compared to traditional PLA

NaveniFlex Kits feature a new proprietary probe design technology providing advantages compared to traditional Duolink® PLA:

  • Enables detection of very low abundant proteins and interactions
  • Only 1/10 of the antibody concentration required
  • Significantly improved signal to noise ratio facilitates quantification

Increased specificity by dual recognition

If a suitable antibody pair is available, the Navinci technology can be used to achieve supreme specificity without background.

Signal Enhancement

The Naveni system features a significantly increased signal compared to conventional IF. Simply replace secondary antibodies with Navenibodies from NaveniFlex MM and RR kits for better results.

Phosphorylation Detection

The Navinci solution allows the detection of posttranslational modifications with unparralleled specificity and no background.

Product Guide

Which NaveniFlex Kit should I choose?

NaveniFlex kits contain Navenibodies (secondary detection antibodies conjugated to proprietary oligo arms) for use with either one or two 1° IgG antibodies raised in mouse (M), rabbit (R) or goat (G). Three fluorophore alternatives are included.

One 1° Ab + NaveniFlex MM or RR

  • Signal enhancement of low abundant targets 
  • In case of insufficient sensitivity

Two 1° Ab + NaveniFlex MR, GR or GM

  • in case of unspecific binding 
  • increased specificity in protein localization
  • investigation of protein interactions 
  • investigation of protein modifications
