Note: Magbeads FastDNA™ Kit for Soil obtained more intact bands of extracted DNA.

Note: The genomic DNA extracted with Magbeads FastDNA™ Kit for Soil (in blue bar) was the only DNA kit among the competitors’ DNA kits to achieve A260/A280 ratio within 1.7- 2.0 across different types of soil samples.

The level of contaminants in the DNA extracted was determined similarly with spectrophotometric analysis by measuring and calculating the ratio of absorbance at 260 nm and 230 nm ( A260/A230). Strong absorbance around 230nm can indicate that organic compounds are present in the purified DNA. A A260/A230 ratio of 1.0 or above 1.0 is generally considered as good level of purity.
