Overview Service Process Examples and Solutions Applications Frequently Asked Questions


RNA interference (RNAi) is a biological process in which small RNA molecules inhibit gene expression by degrading target mRNA. This technique employs small interfering RNAs (siRNAs) or short hairpin RNAs (shRNAs) to target specific mRNA sequences, leading to their degradation and subsequent reduction in protein production. RNAi is a crucial tool for functional genomics, allowing precise and efficient gene knockdown.

Service Process

The process of RNAi involves several critical and interrelated steps:

  1. Target Identification: Selecting the specific genes for knockdown based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of RNAi experiments.
  2. RNAi Design: Designing siRNA or shRNA sequences that specifically target the mRNA of the genes of interest. This step ensures high specificity and efficiency in gene silencing.
  3. Synthesis and Vector Construction: Synthesizing the RNAi molecules or cloning the shRNA sequences into appropriate vectors for delivery into the target cells. This may include plasmids, lentiviral vectors, or other delivery systems.
  4. Delivery of RNAi Constructs: Introducing the RNAi constructs into target cells using methods such as transfection, electroporation, or viral transduction. Efficient delivery is vital for effective gene knockdown.
  5. Selection and Expansion: Isolating and expanding the successfully transfected cells. This selection process may involve the use of selectable markers or sorting techniques to enrich the population of knockdown cells.
  6. Validation: Confirming the efficiency and specificity of gene knockdown through quantitative PCR (qPCR), Western blotting, and functional assays. This step ensures that the gene silencing is effective and that the cells exhibit the expected phenotypic changes.
