This product includes 5 ml of 10 x Reagent D. It is for 2000 assays using 384-well plates or 500 assays using 96-well plates. Cuvettes may also be used for the assay.
The NanoGram DNA Assay Reagent is for measurement of a wide range of DNA or RNA from nanograms to micrograms. The assay is based on the principle that DNA binds to the NanoGram fluorescence dye (Reagent D) and enhances the fluorescence intensity at 535 nm (excitation 485 nm).
The assay reagent (catalog number NDA500) includes 5 ml of 10 x Reagent D. It is for 2000 assays using 384-well plates or 500 assays using 96-well plates. Cuvettes may also be used for the assay.
DNA STANDARD CURVE
1. Dilute the 10 x Reagent D with water 10 fold to make 1 x Reagent D.
2. Prepare a series of standard DNA solutions with concentrations from 0.5 to 100 µg / ml.
3. Mix 10 µl of the DNA solution with 100 µl of the 1 x Reagent D in the wells of a 96-well plate for 5 min.
Data Analysis
Plot the fluorescence intensity Fc and the DNA concentration [DNA] to generate the linear standard curve.
Fc = a [DNA] + b
Where the Fc values are from experimental data, the a and b values are from the linear fitting between the Fc values and the DNA concentrations.
UNKNOWN SAMPLES
Follow the same procedure to measure the fluorescence intensity Fc values from the unknown samples. Calculate the DNA concentrations in the unknown samples using the Fc values from the unknown samples and the a and b values from the standard curve.
