Navinci - Proximity ligation assay (PLA) Portfolio
Innovative in situ proximity ligation assay-based solutions | Immunostaining reinvented
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 (Proximity Ligation Assay) Principle

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.
Key Advantages
A: 10x increased 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
B: Increased specificity by dual recognition
If a suitable antibody pair is available, the Navinci technology can be used to achieve supreme specificity without background.
