EZ Cap Reagent GG (3' OMe) is a co-transcriptional capping reagent for in vitro transcription of 5’ capped mRNA to form a Cap 1 structure.

EZ Cap GG (3' OMe) contains the 5' N7-Methyl-3'-O-Methylguanosine commonly found in mRNA capped by ARCA, whereas EZ Cap GG has a naturally occurring 5' N7-Methylguanosine.

EZ Cap GG (3' OMe) requires a GG initiator, whereas EZ Cap GG (3' OMe) typically provides >90% capped material obtaining a naturally occurring Cap 1 structure. Unlike EZ Cap AG, using EZ Cap GG (3' OMe) is possible to produce transcriptional stuttering and yield in comparable with ARCA.

EZ Cap is compatible with wild-type T7 polymerase. 5 mM EZ Cap and rNTPs is recommended.

Template design is an integral part of any transcription. EZ Cap GG (3' OMe) should be used with a specific initiating sequence 5’ GG 3’.

Final capping efficiency is dependent on the EZ Cap Reagent, DNA template and final mRNA sequence. Secondary structure due to RNA length and base composition could affect final capping efficiency.
