NettetA pH less than 7.0, DNA more readily denatures and precipitates into the organic phase and phase interface, with RNA remaining in the aqueous phase. The aqueous phase containing your RNA is then carefully removed by pipetting (with care not to touch the interface or organic phase, as this can contaminate your sample) and RNA is then …
Nettet21.3.4 Differential Extraction. Differential extraction is a modified extraction technique allowing for the selective lysis and isolation of DNA from a mixture of sperm and epithelial cells (Fig. 21.5 ). Forensic samples, such as those from sexual assault kits, may contain male sperm cells mixed with male and female epithelial cells. NettetDifferential extraction (also known as differential lysis) refers to the process by which the DNA from two different types of cells can be extracted without mixing their contents. …
