A Direct Route to Results: Simplifying Nucleic Acid Workflows with Direct Amplification

What you will learn:

  • How a direct amplification sample preparation approach can be applied to reduce time and consumables required
  • What to expect in your results for direct amplification sample preparation compared to traditional extraction methods
  • How to approach various challenging sample types

Summary

The COVID-19 pandemic highlighted a need for faster sample preparation methods that did not rely on nucleic acid purification from the sample prior to amplification and analysis by RT-qPCR to detect nucleic acid targets. In response, a new sample preparation method was quickly developed to prepare nasopharyngeal swabs for viral detection by RT-qPCR. Following the development of the workflow for this initial sample type, we explored the feasibility of this fast and simple sample preparation method for analyzing other sample types by direct amplification. In this webinar, we discussed not only the original sample preparation method for viral detection from transport media, but also the applicability of this direct amplification sample preparation method for other challenging samples such as FFPE, saliva, blood or plants. 

Laboratories can now begin to look at their sample processing workflow and determine what areas can be improved by eliminating unnecessary, time-consuming steps. Advantages and disadvantages of direct amplification approaches were examined, as well as protocol variations for the different sample types. With these new reagents and methods, labs can now move to improve efficiency and speed time to results by streamlining their sample preparation workflow.
