Step-by-Step Lipid-RNA Conjugation Service Workflow

Project Requirement Assessment

Our expert team first communicates with clients to thoroughly understand the RNA type, experimental or R&D objectives, and delivery requirements. Based on this information, we evaluate the feasibility of lipid conjugation, including lipid selection, conjugation sites, and chemical modification strategies. An initial plan and technical route are proposed to ensure the project is scientifically sound and operationally feasible from the start, providing a foundation for subsequent optimization.

Lipid Design and Screening

According to the characteristics of the RNA molecule and the biological requirements of the target tissue, we design and screen functional lipid structures, including cholesterol, fatty acids, amino lipids, and PEGylated lipids. Small-scale experiments verify the stability, solubility, and bioactivity of lipid-RNA complexes, providing a reliable foundation for large-scale conjugation. Lipid structures are further optimized to enhance cellular uptake and in vivo delivery efficiency.

RNA Chemical Modification

Appropriate modification sites (5' end, 3' end, or bases) are selected based on RNA length and functional requirements. Functionalization strategies, such as amination, thiolation, or click chemistry, are applied to improve conjugation efficiency and RNA stability in vivo, while preserving RNA secondary structure and biological activity. This ensures efficient delivery and robust performance of the RNA molecule.

Conjugation Reaction Optimization

Reaction conditions—including solvent system, temperature, pH, and reaction time—are carefully controlled to achieve efficient conjugation between lipids and RNA. The reaction process is monitored in real-time to prevent RNA degradation, while optimizing the purity and functional activity of the conjugated product, ensuring optimal performance in both in vitro and in vivo applications.

Purification and Analytical Characterization

After conjugation, products are purified and comprehensively validated using HPLC, mass spectrometry, nucleic acid quantification, and structural characterization. Conjugation efficiency, purity, RNA activity, and lipid modification are analyzed to ensure compliance with scientific or industrial standards. Quality control reports and technical documentation are provided when necessary, offering reliable data support for clients.
