In vitro Transcription: INCOGNITO™ IVT and mRNA Production Systems

The new INCOGNITO™ kits

 

Evade cellular immune response  to your RNA with the new INCOGNITO™ kits  from Cellscript.

The new INCOGNITO™ kits *  are designed  for in vitro synthesis of RNA containing modified nucleosides such as pseudouridine and 5-methylcytidine. They assist in reducing immune response and enhancing protein translation.  A range of these kits are available to end users depending on their specific research desires and downstream applications.

Cellscript’s INCOGNITO™ contain everything needed to make N1meΨ- or Ψ-containing Cap1 mRNA, including in vitro transcription reagents plus ScriptCap™ Capping Enzyme, ScriptCap™ 2’-O-Methyltransferase, and A-Plus™ Poly(A) Polymerase.  

The INCOGNITO™ T7-FlashScribe™ N1meΨ-RNA Transcription Kit is specially formulated to enable users to obtain the maximum possible yields of N1-methyl-pseudouridine-containing RNA (N1meΨ-RNA) from an in vitro transcription (IVT) reaction. Although yield varies with the DNA template and other factors, a standard 60 minute, 20 μl reaction will yield up to 160 μg of RNA from 1 μg of the control template. These yields are made possible by the high-performance properties of the T7-FlashScribe™ enzyme. The standard reaction can be scaled up to produce milligram amounts of RNA containing the canonical nucleotides ATP, CTP, GTP and the modified nucleotide N1-methyl-pseudouridine-5'-triphosphate (N1meΨTP).

The INCOGNITO™ T7-FlashScribe™ Ψ-RNA Transcription Kit is specially formulated to maximize yields of pseudouridine-containing RNA (Ψ-RNA) from an in vitro transcription (IVT) reaction. Although yield varies with the DNA template and other factors, a standard 60 minute, 20 μl reaction will yield up to 160 μg of RNA from 1 μg of DNA template. These impressive yields are due to the high-performance properties of the T7-FlashScribe™ enzyme. The standard reaction can be scaled up to generate milligram amounts of RNA containing the canonical nucleotides ATP, CTP, GTP and the modified nucleotide pseudouridine-5'-triphosphate (ΨTP).

 

INCOGNITO™ T7 mScript™ mRNA Production Systems contain everything needed to make N1meΨ- or Ψ-containing Cap1 mRNA, including in vitro transcription reagents plus ScriptCap™ Capping Enzyme, ScriptCap™ 2’-O-Methyltransferase, and A-Plus™ Poly(A) Polymerase. 

 

The INCOGNITO™ SP6 Ψ-RNA Transcription Kit -optimized for high-yield synthesis of pseudouridine-containing RNA (Ψ-RNA) from an in vitro transcription (IVT) reaction.

The INCOGNITO™ T7 5mC- & Ψ-RNA Transcription Kit - optimized for high-yield synthesis of 5-methyl-cytidine- pseudouridine-containing RNA (5mCΨ-RNA) from an in vitro transcription (IVT) reaction.

Advantages

  • Optimized for high-yield synthesis of pseudouridine-containing IVT RNA (Ψ-RNA)
  • Produce up to 100 µg of Ψ-RNA from 1 µg of template ( depending on kit used).
  • Easily scale up reactions to produce milligram amounts of Ψ-RNA.
  • Lower immunogenicity in mammalian cells through incorporation of Ψ in synthesized mRNA.
  • Modified Ψ-mRNAs translate into higher protein levels
  • The standard reactions can be scaled up to produce milligram amounts of RNA canonical nucleotides ATP and GTP and modified pseudouridine-5'-triphosphate (ΨTP) and 5-methyl-cytidine-5'-triphosphate (5mCTP).


 

*Transcription Kits are for in vitro transcription of N1meΨ- or Ψ-containing RNA. - All kits above come with a label license to use them for internal research use under the University of Pennsylvania’s modified mRNA technologies patents.

Product is for research use only (RUO)

Product Description:

The MessageMAX™ T7 ARCA-Capped Message Transcription Kit V2 is optimized for high-yield synthesis of canonical uridine-containing Anti-Reverse Cap Analog (ARCA)-capped RNA from an in vitro transcription (IVT) reaction. A 30 minute, 20 μl reaction yields up to 60 μg of ARCA-capped RNA from 1 μg of the control template DNA. ARCA ensures correct 5′ end incorporation, resulting in RNA that translates more efficiently in vivo than standard cap analogs. ScriptGuard™ RNase Inhibitor is included in the kit to protect synthesized RNA from RNase degradation.

The ARCA / NTP PreMix contains all four ribonucleotides (canonical nucleotides GTP, ATP, UTP and CTP) and the ARCA. The PreMix ensures the optimal concentration of each NTP and ratio of ARCA to GTP (4:1), maximizing transcript capping (~80%) and yield.

MessageMAX™ ARCA-capped RNA can be further processed into mRNA for expression in cells through the use of post-transcriptional capping using CELLSCRIPT™'s ScriptCap™ 2'-O-Methyltransferase (for conversion to a Cap 1 structure) and post-transcriptional tailing using A-Plus™ Poly(A) Polymerase Tailing Kit (available separately).

For reduction of immunogenicity, combine ARCA-capped mRNA with the Min-Immune™ Gold dsRNA Removal Kit to produce virtually dsRNA-free (to <0.005% of sample [LLOQ]), ultra-low immunogenicity mRNA that is suitable for downstream applications such as cell and gene therapy research and mRNA vaccine development.

CELLSCRIPT™ also offers the INCOGNITO™ T7 ARCA 5mC- & Ψ-RNA Transcription Kit to produce low immunogenicity ARCA-capped RNA containing the modified nucleotides 5-methyl-cytidine and pseudouridine.

Materials Supplied:

Important Store at -20°C in a freezer without a defrost cycle. Do not store at -70°C.
