Applications
- Purification of TNA, DNA, or RNA for many applications, including PCR, RT-PCR, cloning, sequencing, Northern and Southern blotting, restriction analysis, and genomic library preparation.
The MasterPure™ Complete DNA and RNA Purification Kit uses a novel technology that enables efficient purification of intact total nucleic acid (TNA), DNA, or RNA from every type of biological material (Table 1 and Fig. 1).
The gentle salt-precipitation protocol permits rapid purification of high-molecular-weight nucleic acids from a single sample or many samples that are processed simultaneously (Fig. 4). High yields of nucleic acids are obtained using MasterPure Kits (Table 2), and yields and purity are highly consistent for different samples of the same material (Fig. 2). The resultant nucleic acids have an A260/A280 ratio of 1.8-2.0, indicating that they are substantially free of protein. The TNA, DNA, and/or RNA purified from different samples can be used directly in many applications. For example, the sensitivity of PCR or RT-PCR assays is often improved if the template is obtained using a MasterPure Purification Kit.
