Probe Synthesis Service | High stability, sensitivity, and specificity, rely on which to obtain a perfect amplification curve.
With the continuous development of chemical synthesis of nucleic acid technology, the use of nucleic acid probes for related research has become one of the commonly used molecular biology techniques in the field of biology and medicine. As the most commonly used signal transduction medium, nucleic acid fluorescent probes have the advantages of high analytical sensitivity, simple detection methods, and less impact on biomolecules. They have been used to detect protein molecules, nucleic acid fragment molecules, small biological molecules, and inorganic ions, etc.

03 The next-generation sequencing (NGS) core material 5rApp probe
With the rapid development of high-throughput NGS technology for small RNAs, the demand for oligonucleotide joints modified by adenylation at the 5' end has greatly increased. 5'-rApp modified joints are mainly used in:
◇ 5' end tag
◇ Activated 5'-pyrimidine-rich RNA
◇As an activated nucleic acid substrate for ribose/deoxyribozymes selected in vitro
◇Broaden the range of RNA substrates that ribose/deoxyribozymes can probe
◇ NGS/miRNA library construction
Diagreat core product—adenosine probe
04 High-sensitivity LNA (locked nucleic acid) probes help RNA research
LNA Oligonucleotides can be synthesized as fully modified LNA sequences, as well as chimeras with DNA, RNA, modified bases, or tags, by conventional phosphoramidite chemistry techniques. LNA probes have extremely high affinity for nucleic acids and single-base discrimination, and can greatly improve detection sensitivity and specificity when used in Northern blotting and in situ hybridization.
Diagreat LNA Probe Synthesis Service
Customized oligonucleotide synthesis services can be provided according to the customer's design sequence or LNA modification requirements, such as modification sites, quantity, and phosphorylation requirements.
