Physicochemical measures of DNA extracted from the NIBSC WC-Gut RR using eight commercial DNA extraction kits, based on the average of five replicates. A DNA yield measured as ng of DNA. B DNA integrity measured using the DNA Integrity Number (DIN). C DNA purity as measured by absorbance ratio at 260 nm/280 nm. The top and bottom of the box represent the third quartile and first quartile data values, while the horizontal top and bottom line at the end of the whiskers show the maximum and minimum data value respectively
