Introduction:
Mutation detection from Formalin Fixed Paraffin-Embedding (FFPE) tissue in molecular lab became a necessary tool for defining potential targeted drug. Accurate quantification of DNA extracted from FFPE tissue is necessary for downstream applications like Polymerase Chain Reaction (PCR), sequencing etc.
Aim:
To check and define which method for FFPE DNA quantification is suitable for downstream processes.
Materials And Methods:
In this experimental experience study Biorad Smartspec Plus spectrophotomery, Qubit Fluorometer, and Qiagen Rotorgene qPCR was used to compare 20 FFPE DNA quantification in Rajiv Gandhi Cancer Institute and Research Centre, in 2015 and quantified amount of DNA used for PCR reaction.
Results:
The average concentration of DNA extracted from FFPE tissue measured using the spectrophotometer was much higher than the concentration measured using the Qubit Fluorometer and qPCR.
Conclusion:
Results varied depending upon the technique used. A fluorometric analysis may be more suitable for quantification of DNA samples extracted from FFPE tissue compared with spectrophotometric analysis. But qPCR is the best technique because it details DNA quantity along with quality of amplifiable DNA from FFPE tissue.
