CleanCap Reagent GG is designed for the cotranscriptional capping of mRNA to produce an mRNA with naturally occurring Cap 1. Cap 1 mRNAs have superior in vivo activity compared to Cap 0 mRNA produced by legacy capping methods such as mCap or anti-reverse cap analog (ARCA).
CleanCap can be used in conjunction with GlpBio's catalog of modified NTPs.
Using the recommended conditions, transcription with CleanCap GG results in 70-90% capped material, generating a Cap 1 structure and gives crude yields of ~1.5 mg per mL of transcription. Final capping is dependent upon the DNA template and final mRNA sequence. Secondary structure due to RNA length and base composition can affect final capping efficiency.
