PCR 即聚合酶链反应，是一种核酸扩增技术，能在体外快速复制 DNA 或 RNA 片段，就像 “分子影印”。1983 年，美国生物化学家 Kary Mullis 突发灵感，后来这项技术让他在 1993 年获诺贝尔化学奖 。

精确扩增对于采用SYBR Green I技术的RT-qPCR的成功至关重要，因为这种染料会结合扩增过程中产生的所有双链DNA。这种一步法试剂含有超纯的AccuStart热 ...

If you'd like to learn more about your health, heritage and family history, an at-home DNA test can help you do just that. Justin Jaffe is the Managing Editor for CNET Money. He has more than 20 ...

Both the DNA and RNA systems are also suitable for downstream applications such as qPCR or sequencing. For DNA analysis, the EMBER™ Ultra DNA Gel Kit offers the highest sensitivity and resolution ...

PCR-machines are used for replication of DNA, detecting DNA sequences, carrying out DNA fingerprinting, forensic analysis, and molecular cloning, diagnosing genetic diseases, and detecting ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

The PIF/Harbinger-derived ADF-IL protein recruits KAT2B to drive its nuclear translocation and local chromatin acetylation, ...

DNA (deoxyribonucleic acid) is the nucleic acid polymer that forms the genetic code for a cell or virus. Most DNA molecules consist of two polymers (double-stranded) of four nucleotides that each ...

From being a promising yet underexplored approach in the 1990s, mRNA therapeutics have evolved dramatically. The discovery of ...

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...
