I see that one of the componets of Product DNAQF, DNA Quantitation Kit, Fluorescence Assay, is a DNA standard. How is the DNA standard prepared? Can it be purchased separately?  
The DNA standard (Product No. D4810) used in the kit is a sheared calf thymus DNA. It is the only one tested with the kit and it is only available in the kit. We do not determine the molecular weight.
How can I ensure accurate initial quantification of the DNA standard by spectrophotometric measurement at A260 when using Product DNAQF, DNA Quantitation Kit, Fluorescence Assay?
The DNA standard (Product No. D4810) should be incubated at 50 °C for 15-30 minutes before determining the concentration spectrophotometrically. This will ensure complete dissolution of the genomic DNA.
What quality of genomic DNA is required for use in Product DNAQF, DNA Quantitation Kit, Fluorescence Assay?
Genomic DNA purified by phenol chloroform extraction is sufficiently clean for use with this kit.
