Creative Bioarray provides a comprehensive non-coding RNA visualization analysis solution. Our service is suitable for the research of gene silencing in the development of therapeutic methods and the biological application of disease pathology research. Use the newly advanced RNA-FISH technology and imaging methods to locate and image related transcripts. At the same time, we also provide a combined IHC and other protein in-situ visual analysis program to realize the multi-level analysis of transcription and translation.
The evidence that non-coding sequences are involved in the regulation of gene expression is becoming more and more comprehensive. In recent years, gene silencing therapy has gradually emerged. Methods to inhibit mRNA expression include the use of single-stranded antisense oligodeoxynucleotides (ASO) and RNA interference (RNAi) using double-stranded short interfering RNA molecules (siRNA). The method of using synthetic oligonucleotides to degrade cellular RNA has been used as a method to study gene function. The ASO used for therapeutic intervention is a single-stranded, chemically modified oligonucleotide with a length of 14 to 20 nucleotides, which has the ability to target genes encoding proteins associated with human diseases. The binding of ASO to the target mRNA results in the spatial inhibition of translation by the ribosomal complex. siRNA targets a specific endogenous RNA sequence by guiding the complex, and then the target RNA transcript is combined and degraded by the endonuclease activity of RISC.

The method of using synthetic oligonucleotides to degrade cellular RNA has been used as a method to study gene function. At the same time, more and more studies have discovered the role of miRNA, siRNA and other sRNAs in the pathophysiology of diseases. The medical application of gene silencing and the research on the function of ncRNA have promoted the increasing demand for single-cell in situ analysis. Our service aims to provide RNA in situ analysis solutions based on highly specific probes. These uniquely designed commercial probe products have highly specific targeting and can be used to understand the expression patterns and functions of non-coding small RNAs. We use commercialized probe products to complete analysis and testing services. The service process includes service negotiation, probe selection or customization, in situ hybridization and imaging, and data analysis.
