Ni-NTA HisSoRS Strips

For assays using His-tagged biomolecules

  • Enhanced signal-to-noise ratio and reproducibility
  • Convenient multiwell-based assay system
  • Reduced optimization for faster assay development

Ni-NTA Strips are 8-well strips whose wells are coated with Ni-NTA. They are used for immobilization of His-tagged proteins in protein interaction assays, such as ELISA.

Product Details

Ni-NTA HisSorb Strips provide the power of the QIAexpress Ni-NTA System in solid-phase 8-well format for convenient assay and screening of His-tagged biomolecules, even if crude lysates. Ni-NTA moieties, which coat the entire surface of each well, deliver effective, directed immobilization of functionally active 6xHis-tagged molecules, leading to more reliable and reproducible assay results and higher signal-to-noise ratio than are possible with other systems.
The QIAexpress, Detection and Assay Handbook, supplied with all QIAexpress detection and assay products, contains detailed example protocols and guidelines for designing and performing assays.

Ni-NTA HisSorb Strips are suitable for a range of applications, including:

  • Quantitation of His-tagged molecules
  • Hybridoma and antibody screening
  • Drug discovery 
  • Screening expression clones and engineered enzymes
