Cap 1 N1meψ BE4max_P2A_GFP mRNA
BEmax is an enhanced cytidine base editor designed to facilitate targeted single-nucleotide conversions in genomic DNA. Recognizing that expression levels significantly impact base-editing efficiency, the optimized the BE4 base editor contains modifications to nuclear localization signals, codon usage, and ancestral reconstruction of the deaminase component. The resulting BE4max editors demonstrate significantly increased efficiency in correcting pathogenic SNPs across a range of mammalian cell types, overcoming previous limitations and offering improved precision in genome editing applications. This mRNA possesses a Cap1 structure, which is highly efficient in capping. It is fully substituted with N1-methyl-pseudo Uridine to improve expression and decrease immunogenicity. Additionally, the mRNA features a 110A tail in its sequence, resembling a mature mRNA.
