Isothermal Nucleic Acid Principle Summary
This kit is based on a rapid nucleic acid amplification technology at room temperature and constant temperature: at room temperature and constant temperature (generally 39℃~42℃), with the help of auxiliary proteins and single-strand binding proteins,the recombinase and primers form a complex;Source search and combine the target homology domain, at this time,a D-loop region is formed at the homology position and strand exchange begins;along with the dissociation of the recombinase from the complex,the polymerase also binds to the 3′ end of the primer and begins chain extension. At the same time, relying on the function of exonuclease, adding specific molecular probes designed according to the template, and using fluorescence monitoring equipment can realize real-time monitoring of the amplification process of the target fragment.

The 23S ribosomal RNA (rRNA) is a crucial component of the bacterial/archean ribosome. The 23S rRNA is a 2,904-nucleotide long component of the large subunit (50S) of the ribosome. Compared to 16S rRNA genes, 23S rRNA genes have greater sequence variations due to unique insertions, deletions, and length. Attogene’s 23s PCR kit is designed for identification of specific strains of bacterial/archean using the ribosomal RNA gene region for use in Phylogenetic studies of bacterial diversity from environmental DNA samples such as water. For example, a sample of algae is obtained and washed to extract a clean algal genomic DNA (gDNA) sample. A reaction mixture is assembled from primers, master mix, and gDNA samples as required. The qPCR machine of choice is set up and loaded as needed and the mixture undergoes PCR amplification. The Primer mix provided exploits the Taq polymerase to amplify the gene region of interest.
