for your experiment
The Invitrogen™ Qubit™ 4 Fluorometer with Wi-Fi is designed DNA HS
to quickly and specifically quantitate DNA or RNA.
DNA BR
ssDNA
Key features include:
• Invitrogen™ Qubit™ assay dyes bind selectively to miRNA
DNA, RNA, or protein, making it more sensitive than RNA BR
UV absorbance
RNA HS
• Uses as little as 1 μL of sample, even with very UV
dilute samples

• Fast, reliable detection of degraded RNA with the Quantifiable range (µg/mL)

ranges for the Qubit assays vs. UV absorbance measurements.
• Integrated reagent calculator to quickly generate working UV absorbance readings are not selective for RNA vs. DNA.
solution calculations
• Flexible options for exporting results: Wi-Fi, USB drive, or
direct connection with a USB cable
Features of Qubit assays
• Kits contain concentrated assay reagent, dilution buffer, • All assays are performed using the same general
and prediluted standards protocol with a simple mix-and-read format
• Dyes fluoresce only when bound to the target of interest, • Only 2 minutes of incubation time required for DNA and
minimizing the effects of contaminants—including RNA assays
degraded DNA or RNA—on the result
