ELISA troubleshooting

Hundreds of variables influence ELISA data. Below is a collection of general assay running tips and troubleshooting strategies that you may find helpful when trying to resolve ELISA issues. For Q-View Data Analysis tips, please see http://www.quansysbio.com/data-analysis-q-view.

When running a Q-Plex™ Array:
  • DO be exact when calibrating shaker speed, being off by even 100 RPM can affect results
  • DO dilute all sample types at least 1:2 (50%) with sample diluent (except cell culture media, which can be tested NEAT)
  • DO load all standards and samples into the microplate within 10 minutes of each other
  • DO be exact with incubation times, particularly the SHRP incubation
  • DO be exact when mixing Substrate A and B, being off by even 50 µL can affect results, and mix thoroughly
  • DON’T allow the plate to dry out between steps, particularly between washing SHRP and adding substrate
  • DON’T allow the SHRP, substrate, or IR dye to be exposed to UV light, as this may degrade it
  • DON’T analyze from a color or jpeg image; save grayscale images using a lossless image file type such as Tiff or RAW
