DENARASE ELISA Kit - available now!

Best in class performance
The carefully selected monoclonal antibodies provide an unmatched sensitivity and reproducibility in comparison to similar endonuclease ELISA Kits that work with polyclonal antibodies.

Best sensitivity
Endonuclease concentrations in final pharmaceutical product are often below the limit of detection of previous state-of-the-art kits. These values may raise uncertainty, as low signals as a result of material failure or human error cannot be excluded. However, with the DENARASE® ELISA Kit you can detect and quantify up to 30 times lower endonuclease concentrations compared to competitor ELISA Kits. This makes the assay extremely reliable, even when expected concentrations are at a very low level.

Best reproducibility
The highly specific monoclonal antibodies provide excellent reproducible results in both inter and intra assays. This enables an easy uptake in routine applications and avoids repeats in case of unclear results.

Broad working range
The broad working range of the Kit enables a convenient handling of samples as over-dilution is unlikely to happen.

Save time
Save up to 50% time compared to competitor kits.
