OF-02
Based on 1 Customer Validation
OF-02 is an ionizable lipid for mRNA delivery and a key component of lipid nanoparticles (LNPs). OF-02 is protonated in the acidic endosomal environment to promote endosomal escape of mRNA and efficiently induce protein expression in target cells. OF-02 relies on the pH-responsive membrane fusion properties to form a complex with mRNA and destroy the endosomal membrane structure to achieve mRNA release in the cytoplasm. OF-02 is mainly used in the development of mRNA vaccines, gene editing, and protein replacement therapy[1][2][3].

Biological Activity
Description
In Vitro
OF-02 (1-50 μM lipid concentration; 48 h) formed LNPs with a particle size of approximately 100 nm and a PDI of <0.2 in vitro, with an mRNA encapsulation efficiency of over 90% and low cytotoxicity[1][2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.
In Vivo
OF-02 (0.75 mg/kg; intravenous injection; single dose; 24 h) shows liver-dominant biodistribution in luciferase mRNA delivery experiments, with some expression in the spleen[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocols

Gene Editing
Gene editing modify specific sites within the genome through gene deletions, insertions or conversions to study functionally unknown genes or conduct gene therapy. It is also used to change the biological traits of organisms to establish new varieties. Gene editing techniques include zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas 9) (CRISPR/Cas9).

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Western Blot
Western blotting (WB) is a commonly used experimental method in molecular biology, biochemistry, and immunogenetics for identifying and quantifying target proteins. It combines gel electrophoresis with immunoassay, enabling researchers to analyze protein expression, post-translational modifications, and molecular weight.

CRISPR-Cas9 editing of human pluripotent stem cells
CRISPR-Cas9 editing of human pluripotent stem cells uses a guide RNA to direct Cas9 to a genomic target, where Cas9 creates a double-strand break that is repaired mainly by non-homologous end joining for knockout mutations or by homology-directed repair when a donor template is supplied for precise knock-in or sequence correction. The readout is generated by genotyping edited bulk populations or single-cell-derived clones, using PCR, sequencing, restriction-based assays, reporter fluorescence, or allele-specific analysis to distinguish unedited alleles, indels, precise donor-mediated edits, biallelic deletions, and unwanted on-target lesions.

Protocol For Protein Expression And Purification
Recombinant protein expression in Escherichia coli followed by purification of a His-tagged soluble protein by immobilized metal affinity chromatography (IMAC), with optional MBP fusion and TEV tag removal when the construct includes these elements. The biological readout is production of the encoded target protein, detected as an inducible band at the expected molecular mass by SDS-PAGE and quantified by total protein assay or chromatographic absorbance; the purification readout is enrichment of the target protein in elution fractions after selective binding of polyhistidine residues to immobilized Ni2+/metal-chelate resin and elution by imidazole-containing buffer. Expression is driven by an inducible bacterial expression system, commonly T7/lac-based, in which IPTG or lactose/auto-induction activates transcription and translation of the cloned gene; lower induction temperature, lower inducer concentration, induction timing, and solubility-enhancing fusion tags can influence the frac
