Probe Synthesis

Nuclei acid probes are sequences of single stranded DNA or RNA fragments that have the potential to bind specifically to their complementary nucleic acid sequences through a process called hybridization. Nuclei acid probes are usually labeled with a detectable moiety such as radioisotopes, epitopes, fluorophores, or biotin to facilitate the detection of their respective target molecules. More recently, nuclei acid probes are becoming a routinely used tool in various research areas. This increased prevalence is due to the increased availability of nuclei acid sequences in databases and advances in molecular biology, such as PCR and NGS. A few examples of these advances include: molecular diagnosis, chip sequencing, human genome engineering, tumor research, forensic identification, precision medicine, IVD, etc.

With our propriety synthesis platform and professional research team, Synbio Technologies is able to produce high quality nucleic acid probes with batch consistency for both routine and specialized applications. Additionally, we can provide a wide variety of modifications or labeling at the 5′ and 3′ ends or a designated position of the probe according to the specific need of our customers.

Case Studies

Purity is one of the main factors affecting the effectiveness of a nucleic acid probe. Synbio Technologies’ advanced and optimized purification techniques can maximize the elimination of remaining raw materials and other impurities from the target probe, as illustrated below.

Figure 1. The spectrum shows the peak of probe product purified with the conventional method. ☆ represents the target product and O represents impurities. The spectrum shows that impurities were not successfully separated from the target product.**
Figure 2.This spectrum shows the peak of probe product purified with Synbio Technologies’ optimized purification method. ☆ represents target product and O represents impurities. The spectrum shows that impurities were further separated from the target product.**
