よくあるご質問（FAQ）

Why am I getting negative fluorescence values with my Qubit Assays?

Negative fluorescence is a physical impossibility. It is an artifact from software autocorrecting for background signal. This means your reader is picking up and subtracting out background light at the cost of your data. Make sure to do a buffer-only control and assess the type of signal. You may need to switch to a different plate.

I have a Quant-iT DNA Kit and want to use it for the Qubit Fluorometer. Can I?

Yes, the manual has directions for this application. You will use the 0 ng/µL lambda dsDNA HS standard to generate Standard #1. You will prepare a dilution of the 10 ng/µL lambda dsDNA HS standard to generate Standard #2. You then prepare the samples and compare them to this 2-point standard curve. The Quant-iT dsDNA BR Kit can be used in a similar manner.

What is the useful pH range for Quant-iT DNA kits?

The buffer included in the kit should assure the proper pH range, even if your DNA is at a pH outside of this range, since at least a 10-fold excess of kit buffer over sample is used in the assay.

I'm trying to quantify some DNA labeled with a fluorophore. Will this work?

PicoGreen dye and other fluorescence-based quantification reagents are not recommended for quantifying dye-conjugated nucleic acids. The attached dye molecules can interfere with either binding and/or fluorescence output of the quantification reagents.

Does DNA length have an effect on the dsDNA assays?

Strands that are roughly in the 20-mer range or shorter show a lower level of signal. For dsDNA samples that are composed of mostly short strands, the reagent may still be used, but one should use a dsDNA standard that is of comparable length as the sample.

BACKGROUND AND AIMS: The intestinal bacterial microflora plays an important role in the aetiology of inflammatory bowel disease (IBD). As most of the colonic bacteria cannot be identified by culture techniques, genomic technology can be used for analysis of the composition of the microflora.
