To Nanodrop or Not to Nanodrop: Choosing the Most Appropriate Method for Nucleic Acid Quantitation

  • Review current DNA/RNA quantitation methods, including absorbance, fluorescent nucleic acid-binding dyes and qPCR
  • Learn about the advantages and disadvantages of each method 

Summary

Accurate and reliable nucleic acid quantitation is a critical step in DNA and RNA analysis workflows.  Often success or failure in downstream applications simply comes down to whether or not the appropriate amount of input nucleic acid is used.  There are a number of key considerations when quantifying nucleic acids with the goal being to obtain not only an accurate measurement of yield/concentration, but often integrity and purity as well. Not all quantitation methods reveal the same information about a sample, so understanding the strengths and weaknesses of each method allows a researcher to choose an appropriate method based on the starting sample type and downstream assay. This webinar will review current quantitation methods including absorbance, fluorescent nucleic acid-binding dyes and qPCR.  The advantages and disadvantages of each method will be discussed including data from samples that were quantitated using multiple methods to highlight the differences in these methods. Ultimately, no single quantitation method is ideal for every situation, and after this webinar, you will be able to choose the appropriate method required for downstream application success.
