Invitrogen Quant-iT assay kits utilize advanced fluorophores that become fluorescent upon binding to DNA, RNA, or proteins; the fluorescence intensity of the resulting complex depends directly on the amount of the target molecule in the sample.

High-sensitivity fluorescence detection of nucleic acids or protein for 96-1536 samples can be quickly performed on Fluoroskan or Fluoroskan FL Microplate Fluorometer or Varioskan LUX Multimode Microplate Reader using Invitrogen reagents for optimal detection. Take advantage of automatic dynamic range selection to get optimal gain settings for each individual well and automation capabilities for even higher throughput.
Read about detection limit (LOD) as low as 0.04ng of DNA in this featured application note highlighting sensitive fluorescence detection of DNA capabilities when you combine Quant-iT technology with a Fluoroskan plate reader.

* Invitrogen Quant-iT assays and reagents can also be used with the Invitrogen Qubit Fluorometer. †The useful range assumes a 1–20 µL sample volume in a 96-well microplate assay. ‡ Excitation (Ex) and emission (Em), in nm, of the Quant-iT detection reagent.
For everyday needs when quantitating 1–20 samples, use Invitrogen Qubit Assays for use with the Qubit fluorometers. Ideal for cloning, sequencing, transfection, qPCR, microarrays, protein gels, Western blots and protein activity assays. See how easy it is to use the latest version of the Qubit - the Qubit 4 fluorometer.
