Comparison of yield of DNA from 400 µL, 200 µL, 100 µL, 50 µL and 25 µL human saliva samples (in triplicates) extracted using three different extraction kits i.e., AccuPrep® Genomic DNA Extraction Kit, Qiagen QIAamp DNA Mini Kit, and Qiagen miRNeasy Tissue/Cells Advanced Micro Kit. Quantification of DNA was performed using a NanoDrop-1000. Error bars represent the range of values from technical replicates. Statistical significance is indicated as follows: ***P < 0.001, **P < 0.01
