EGFP (enhanced green fluorescent protein) mRNA can express an enhanced green fluorescence once has been transfected into cells, which makes it always used as a direct detection reporter mRNA. You can observe the fluorescence at 509 nm. Our product had already been modified with ARCA with a high efficient co-transcriptional capping method, which means most of mRNA has a Cap 0 structure. It is a more mature mRNA than mRNA with no capping and maintain a more stable state which lead to higher expressing efficiency in transfected mammalian cells. ARCA obtain the ability only inserting in the proper orientation, results in forming mRNAs that can be translated twice efficiently as those initiated with mCAP. Other sizes are available.
