Microarray and sRNA Expression Profiling

Small regulatory RNA (sRNA) is widely distributed in archaea, bacteria, and eukaryotes. It is a new type of endogenous non-protein coding RNA with a length of 21-35 nucleotides. sRNA mainly includes microRNAs (miRNAs), small interfering RNAs (siRNAs), small nucleolar RNAs (snoRNAs), siRNAs, Piwi-interacting RNAs (piRNA). Bacteria contain a variety of sRNAs, some of which have "housekeeping" functions, while other types of sRNAs play a regulatory role in gene expression. The cis-encoded RNA regulator is usually a part of the mRNA, located in front of the protein-coding region, and changes the expression of the corresponding protein by binding to small metabolites. Other regulatory RNAs are transcribed in trans from a separate promoter located in the intergenic region (IGR) or the opposite strand of the protein-coding region (ie, antisense RNA). The trans-encoded sRNA targets mRNA through short and imperfect sequence complementation, thereby regulating the expression of its target, and plays an important role in controlling bacterial stress response and adapting to changing environments.

Service Process

The use of microarrays to discover the function of sRNA requires simultaneous analysis of non-coding sRNA and protein-coding transcripts (i.e. mRNA). Our sRNA microarray service is optimized for the detection of small transcripts. The probe design adds many trans-sRNA complementary probes to the detection coding sequence, and the detection range is expanded on the basis of the established transcription map. Our sRNA microarray service currently mainly targets model microorganisms such as E. coli. If you are interested in sRNA analysis of other model organisms, you can also choose to order sRNA microarray printing services. We have designed multiple probes to detect the known trans-encoding sRNA transcripts of the samples. The data comes from the open transcript database and our own library. The specific service process is customized service content, microarray design and printing, microarray detection, and data analysis.
