QuantaWell QuantaWell2 microplates are standard microplates coated with metal nanoparticles that enhance fluorescent signals via a plasmonic effect.  These plates can be used to run fluorescent immunoassays and will deliver a 20 – 50-fold enhancement in the intensity of the fluorescent signal and a 2 order of magnitude increase in dynamic range (see examples below).   They offer:

  • 20x – 50x increase in fluorescent intensity
  • 2 order of magnitude increase in dynamic range
  • rapid protocol:  complete in under 3 hours
  • save money:  no need for HRP substrates
  • can be used with most fluorophores, most plate readers, most buffers and  50% human serum

Recommended Protocol.     Coat plate with 2 – 5 ug/mL of capture antibody.  Wash.  Block with 3% BSA.  Wash.  Incubate with sample or standard.  Wash.    Incubate with biotinylated detection antibody.  Wash.  Incubate with streptavidin-conjugated dye.  Wash.  Read.

Serum Compatibility.  These plates can be run in 10% fetal bovine serum (FBS) and in 50% human serum (HS).  See Figure 1.

Recommended Dyes.  Of all of the dyes we tested, we found streptaviding-conjugated Sure-Light P1 to deliver the highest sensitivity.  Please contact us to obtain this dye.  All other dyes yield satisfactory results.

Recommended Fluorescent Plate Readers.  QuantaWell 2 plates will work well in most plate readers but will not work in the Victor (PerkinElmer) readers.

Storage.  QuantaWell 2 plates can be stored at room temperature for up to 6 months.
