DNA/RNA Extraction Reagents in Plant Research

Time:2020-11-02 09:24:43 View:

DNA/RNA extraction is usually the first step required for most molecular biology investigations in plant research. Plants present some unique challenges compared to animal tissues in DNA/RNA extraction. For example, the tough cell wall of many plant tissues often requires time-consuming enzymatic or mechanical techniques to break apart. In addition, other problems may be encountered including the presence of large quantities of polysaccharides; high levels of RNases; various different kinds of phenolics, including tannins; low concentrations of nucleic acids (high water content); tissue, such as lignin (wood), that is difficult to break up; and so on. To overcome these problems and difficulties, TransGen provides both silica-based spin column method and modified CTAB method tailored for plant DNA/RNA extraction. Furthermore, soil DNA extraction reagent based on magnetic bead method is also available.
