Co-transcriptional Capping Method
Selection of UTRs
For improving RNA expression at specific organs
Optimized PolyA Vector
For stable expression of polyA containing plasmid
The GS 2′-O-Ethyl-capped mRNA delivers the highest and most durable expression profile among all tested cap analogs, making it an optimal choice for in vivo applications requiring sustained protein output.
GenScript patented Capping Technology has a novel improved co-transcriptional capping method to make mRNA, yielding mRNA with high capping efficiency, high integrity and more homogenous 5’end .
GenScript Cap™ mRNA Structure
GenScript Capping™ Technology Benefit
The GenScript Cap™ optimized IVT method ensures the production of high-integrity mRNA, resulting in enhanced mRNA expression.
Fluc mRNA Purity mRNA integrity by Bioanalyzer
Fluc mRNA Expression in A549 Cells
Novel 2’-O-Ethyl-capped RNA showed higher expression than natural Cap1 RNA, and slower clearance rate in vivo.
Optimizing UTR Selection for Tissue-Specific Enhanced mRNA Expression
The GenScript Cap™ optimized IVT method ensures the production of high-integrity mRNA, significantly reducing its immunogenicity.
The Optimized PolyA vector technology facilitates the stable incorporation of polyA sequences into plasmids. The uniformity of the polyA tail is crucial, as it significantly influences mRNA expression efficiency.
Poly(A) Tail integrity Compared with other vendors
The length of the polyA tail significantly impacts mRNA
expression
efficiency in cells, with tails longer than 80 adenines (80As) typically being
preferred.

Cap 2 Technology
CircRNA Platform
saRNA Platform
GenScript developed novel Cap2 technology that marks a groundbreaking advancement in the field of mRNA research, enhancing the stability and translation efficiency of mRNA molecules.
Cap2 RNA was reported to have better expression than Cap1 RNA in stressed condition*. By improving the efficacy and durability of mRNA constructs, Cap 2 technology paves the way for more effective treatments in the development of mRNA-based therapeutics and vaccines.

ARCA-GenScript Cap 2 mRNA
mRNA Expression Without Stress
mRNA Expression Under Stress Conditions
Cap0: positive sense RNA viruses such as alphaviridae-like virus RNA mainly uses cap0 mechanism.
Cap1: crucial for mammalian cells to distinguish self or non-self mRNAs during viral infection
Cap2: Cap2 impacts the protein production in a cell-specific manner and contributes to RNA immune evasion
