EFFECTS OF INSTRUMENT RESOLUTION ON ASSESSMENT OF DNA PURITY

The traditional method for quantification and assessment of purity of DNA samples is spectrophotometric measurement at 260 and 280nm . It is generally accepted that a sample of pure, double-stranded DNA of 50 g/mL will have an absorbance at 260nm of 1.0 and that the ratio of absorbance at 260 and 280nm of this...

Ten resolutions that could produce a happy new (tech) year

Wisconsins real-time economy kept pace with a globally paced clock in 2004 as the state became better known as a place where innovation, intellectual property and investment are welcome. Dont pop the Champagne corks just yet: Wisconsin still has a long way to go before its economy is creating as many high-wage jobs as the state lost in the three-year manufacturing recession. The chasm be...
