基本信息
General description【一般描述】 | Exonucleases remove a single nucleotide or an oligonucleotide at the 5′ or 3′ end. Exonuclease, such as Three Prime Repair Exonuclease 1 (TREX1), plays an important role in proofreading of DNA amplification and removal of damaged DNA. Deficiency of TREX1 enzyme has been shown to trigger the autoimmune disease Aicardia-Goutieres syndrome. TREX1 expression has been reported to correlate with cervical cancer cell growth and disease progression. In addition, 3′ exonucleases are often used as tools in molecular biology such as site-directed mutagenesis and the generation of single stranded DNA probe |
Features and Benefits【特点和优势】 | 3′ to 5′ Exonuclease Activity Assay:
|
Principle【原理】 | In this assay, exonuclease digests the provided DNA probe, producing a strong fluorescent signal (λEx = 304 nm/λEm = 369 nm). The kit is simple, sensitive, high-throughput adaptable and can detect as low as 0.2 μU of exonuclease activity. |
