Quantikine® HS Colorimetric Sandwich ELISA Kits - Quantikine ELISA Kits

Quantikine ELISA Kit

Quantikine High Sensitivity ELISA Kits are complete assays generally used when very low levels of the target protein are expected. These kits utilize distinct protocols to achieve their impressive levels of analyte detection.

Features

  • Detect femtogram levels of protein
  • Complete ready-to-use kits
  • Exhaustively tested for superior quality and reproducibility
  • Detailed protocol booklets include inter- and intra-assay precision, recovery, linearity, sensitivity, and sample value data
  • Colorimetric detection
 

With the amplification system shown in Figure 1, an alkaline phosphatase-based amplification leads to the formation of a colored product. Other kits utilize a polymeric streptavidin-HRP conjugate as shown in Figure 2. Please refer to Product Datasheet for kit-specific information.

High Sensitivity ELISA Kit Application Examples

Cytokine Release Syndrome (CRS) is a well-known consequence of viral infections such as influenza and COVID-19. It is also an adverse response to cell therapy. IFN-γ secretion is an early and prominent feature of CRS that stimulates a myriad of downstream responses. To learn more about how our high sensitivity ELISAs are used in this space read our IFN-gamma in CRS immunoassay application note.
