Figure 6From: Measuring microRNAs: Comparisons of microarray and quantitative PCR measurements, and of different total RNA prep methodsAbsorption Spectra of HeLa and ZR-75-1 Sample Preps. The absorption spectra for the total RNA sample preps (listed in Table 1) are shown. Blue traces are HeLa cell preps and red traces are ZR-75-1 cell preps. Spectra are from 220 to 350 nm.Back to article page
