RNA editing services offer a cutting-edge approach to modifying RNA sequences within cells, providing researchers with powerful tools to study gene expression, protein function, and disease mechanisms. Unlike DNA editing, RNA editing allows for reversible and dynamic modifications, enabling precise control over gene expression without altering the underlying genetic code. Our RNA editing services provide comprehensive solutions for designing, constructing, and validating edited RNA sequences tailored to your specific research needs.

Overview Service Process Examples and Solutions Applications Frequently Asked Questions

Overview

RNA editing involves the targeted modification of RNA molecules to alter their nucleotide sequence. This can be achieved using techniques such as adenosine-to-inosine (A-to-I) editing or cytosine-to-uridine (C-to-U) editing, mediated by engineered enzymes like ADARs (adenosine deaminases acting on RNA) or other RNA-targeting proteins. RNA editing allows researchers to precisely modify RNA transcripts, thereby influencing protein production and function, studying RNA biology, and developing RNA-based therapeutics.

Service Process

The process of RNA editing involves several critical and interrelated steps:

Target Identification: Selecting the specific RNA sequences for editing based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of the RNA editing process.
Guide RNA Design: Designing guide RNAs that direct the RNA-editing enzymes to the precise RNA sequences. This step ensures specificity and accuracy in editing.
Enzyme Engineering: Using engineered enzymes, such as ADARs or other RNA-editing proteins, to achieve the desired RNA modifications.
Vector Construction: Cloning the guide RNAs and RNA-editing enzymes into appropriate vectors for delivery into target cells.
Delivery of Editing Components: Introducing the RNA-editing constructs into target cells using methods such as electroporation, viral vectors, or lipid nanoparticles. Efficient delivery is vital for successful RNA editing.
Selection and Expansion: Isolating and expanding the successfully edited cells. This selection process may involve the use of selectable markers or advanced sorting techniques to enrich the population of edited cells.
Validation: Confirming the presence and accuracy of the RNA modifications through sequencing and functional assays. This step ensures that the edits are precise and that the cells exhibit the expected phenotypic changes.
