快速提取™，™RNA提取解决方案
The QuickExtract RNA Extraction Solution is a fast，simple way of preparing RNA for RT-PCR（both endpoint and real-time）。This kit uses a single-tube system with non-toxic reagents that only requires vortex mixing to lyse the cells and prepare the RNA for cDNA synthesis。The kit works with cells from human samples。It is however not suitable for tissue samples。An optional DNase I treatment may improve certain downstream applications。
Example应用程序：cDNA synthesis for PCR and NGS applications，end-point and real-time RT-PCR。

mag™，™and sbeadex™，™Kits
The mag and the sbeadex kits（e.g.sbeadex blood，sbeadex forensic，mag mini/maxi and mag nanogram）use magnetic beads to purify DNA from avariety of blood sample types such as EDTA heparin，citrate and buffy coats as well as swab matrices，tissue and forensic samples。They support automated DNA extractions using magnetic particle handlers，as well as liquid handlers。While our mag kits are based on proven，conventional magnetic beads，sbeadex kits use an innovative next-generation technology of double-coated magnetic beads thatyield improved DNA quality and omit enzyme inhibiting organic solvents in the final eluate。
mag and sbeadex kits are right for you if:
- Highly purified nucleic acids are required fora variety of downstream applications like PCR or NGS。
- Afully automatable solution is needed to support high-throughput workflows。
Example应用程序：Enzymatic fragmentation in NGS applications，PCR analyses，Sanger sequencing。
