Reporter genes are commonly used in cell biology research. OZ Biosciences offers reporter mRNAs that can be used as controls to study transfection and expression in mammalian cells using a variety of assays. They mimic fully processed mature mRNA. These mRNAs are produced by in vitro transcription and stabilized at the 5' end by modified nucleotides capping (Cap1). They contain a poly(A) tail at the 3' end and are also optimized to yield improved stability and performance. Available as unmodified or modified versions: modified with 5-methoxyuridine (5moU replaces U) to reduce innate immune responses, modified with N1-methyl-pseudouridine (N1-m?) to reduce innate immune response, or labelled with Cy5 so they can be easily traced to analyze mRNA delivery and translation efficiency.
