QuicKit ELISA Validated Sample Types

Quantikine QuicKit ELISAs are extensively optimized to reduce matrix effects that are commonly seen with complex sample matrices. The following sample types have been validated for use in these ELISA kits:

  • Serum
  • Plasma
  • Cell Culture Supernates

 

QuicKit ELISA Kit Components

These colorimetric ready-to-use ELISAs come with all components necessary to run your assay. Kit contents may vary slightly. Please refer to product-specific inserts for a complete list of contents for each individual assay:

  • Anti-Tag coated plate
  • Tag-conjugated capture antibody concentrate
  • HRP-conjugated detection antibody concentrate
  • Assay Diluent
  • Calibrator Diluent
  • Standard
  • 25X Wash Buffer
  • Substrate
  • Stop Solution

 

ELISA Assay Principle

These assays utilize an anti-tag coated microplate. Standards, samples, and controls are added to plate, followed by subsequent addition of an antibody cocktail. Following a 1 hour incubation, plates are washed and substrate is added and incubated for 20 minutes. Stop solution is then added and plates are read using a standard microplate reader.

In an ELISA assay, the antigen must be immobilized to a solid surface. The antigen is then complexed to a detection antibody conjugated with a molecule amenable for detection such as an enzyme or a fluorophore.

Data You can Trust

Although Quantikine® QuicKitTM ELISAs produce results in a fraction of the time of traditional ELISAs, quality data is not sacrificed for speed. QuicKits maintain similar standards for quality that you have come to expect from the gold-standard Quantikine ELISA brand.

 

Linearity of Dilution

Linearity of dilution is a hallmark of the R&D Systems® Quantikine® ELISAs and QuicKits are no exception. Linearity is important for assessing matrix effects, confirming that the QuicKitTM ELISA accurately measures sample values. Poor linearity of dilution or extreme deviation from 100% indicates that matrix effects can artifactually enhance or interfere with analyte detection.

Spike and Recovery

In spike and recovery experiments, natural samples are spiked with the recombinant target analyte of interest to identify interference caused by sample matrices. Matrix effects occur when a substance in the sample interferes with the accurate detection of a target analyte. Matrix effects are caused by biological phenomena such as non-specific antibody binding, antibody cross reactivity or interference. Spike and recovery experiments are an important tool for assessing the accuracy of your measurement.
