Description: HiExpress Cre IVT mRNA (m1Ψ) is a specialized in vitro transcribed (IVT) messenger RNA designed to express the Cre recombinase enzyme, a powerful tool for genetic manipulation and gene editing. Cre recombinase is a tyrosine site-specific DNA recombinase that facilitates precise DNA recombination events. It selectively recognizes and recombines two loxP DNA sequences, which are 34-bp asymmetric sites featuring a pair of palindromic recombinase binding elements and an asymmetric spacer region. The recombination process involves the assembly of a tetrameric synaptic complex, cleavage of opposing DNA strands, and formation of a Holliday junction intermediate, ultimately leading to the generation of recombinant products. This IVT mRNA incorporates N1-methylpseudouridine (m1Ψ), which enhances mRNA stability, reduces immunogenicity, and improves translation efficiency. The mRNA is capped with Cap1, and has a poly(A) tail, further enhancing its stability and translation efficiency. These modifications ensure high levels of Cre recombinase protein expression, making it suitable for applications requiring precise genetic manipulation, such as conditional gene knockout, gene expression studies, and the development of genetically modified organisms. Cre recombinase has been widely used in biotechnology applications for precise removal or replacement of defective DNA through a highly controlled process that avoids DNA lesions, making it an effective gene editing technology. The use of IVT mRNA for transient expression of Cre recombinase provides a flexible and efficient platform for these applications, reducing the risk of long-term side effects associated with viral vector-based methods.
