What is DNA quantification used for?
DNA quantification and RNA quantification, generally referred to as nucleic acid quantification, is commonly performed to determine the average concentration of DNA or RNA in a sample prior to proceeding with downstream experiments.
What are quantification kits?
The kits evaluate sample quality and quantity in a single reaction. See products. The Applied Biosystems Quantifiler HP DNA Quantification Kit enables forensic laboratories to simultaneously obtain a quantitative and qualitative assessment of total human DNA in a single, highly sensitive real-time PCR reaction.
What are the methods of quantification of DNA?
Comparison of DNA quantification Methods
| Method | Sensitivity |
|---|---|
| UV spectrophotometry | 2 ng/µL (typical, with microvolume spectrophotometer) |
| Diphenylamine method | 3 µg |
| Fluorescence measurement | 10-50 pg/µL (typical, depending on kit used) |
| Electrophoresis | 10 ng (typical, depending on specific ladder and imaging conditions) |
How do you quantify DNA after extraction?
Spectrophotometry and fluorometry are commonly used to measure both genomic and plasmid DNA concentration. Spectrophotometry can be used to measure microgram quantities of pure DNA samples (i.e., DNA that is not contaminated by proteins, phenol, agarose, or RNA).
How do you quantify DNA and RNA?
The DNA or RNA sample is measured using a fluorometer, and nucleic acid concentrations are then calculated by comparing fluorescence emission of the sample to a fluorescence curve generated using standards of known nucleic acid concentration.
What is Kapa qPCR?
Overview. KAPA Library Quantification Kits contain all the reagents needed for the accurate, reliable and reproducible qPCR-based quantification of next-generation sequencing (NGS) libraries prepared for sequencing on Illumina platforms.
Is PCR DNA quantification?
Real-time PCR is the technique of choice for nucleic acid quantification. In the field of detection of genetically modified organisms (GMOs) quantification of biotech products may be required to fulfil legislative requirements.
Which reagent is used for quantification of DNA?
Fluorescence detection with Hoechst 33258 reagent is a sensitive and precise method for DNA quantification if the G+C content is less than 50%. In addition, this method allows quantification of very low levels of DNA (nanogram scale). Moreover, the samples can be crude cell extracts.
What is Kapa quantification?
The KAPA Library Quantification assay consists of repetitive pipetting steps, which can easily be automated. The use of an automated liquid handling system is highly recommended for high-throughput NGS pipelines. Please refer to the KAPA Library Quantification Technical Guide for more information.
How reliable is NanoDrop?
At higher dilutions (sixteen fold and above, DNA concentration range: 1.35–0.16 ng/μl), quantification by NanoDrop was neither precise nor accurate, while quantification by Qubit was found to be precise and close to estimated concentration of DNA at the tested dilution.
