2’-O-Methyl-A(Bz)-Suc-CPG is used for synthesis of oligonucleotides that contain nuclease resistant 2’-O-methyl linkages to prevent degradation. The 2’-O-Methyl-A(Bz)-Suc-CPG requires no special handling or deprotection reagents. The 500 Å CPG is best suited for the synthesis of RNA sequences up to 50-mers in length.

Properties:

  • Appearance:

    white powder

Product Usage:

  • Synthesis Conditions:

    Follow the instrument manufacturer's protocol when using this product.

  • Cleavage Conditions:

    Use concentrated ammonia for 90 minutes at 25°C or for 30 minutes at 60°C. When using fast deprotecting amidites( CAc; GDMF) 1:1 ammonia:methylamine (AMA) for 25 minutes at 25°C may also be used.

  • Deprotection Conditions:

    When using fast deprotecting amidites (eg. C-Ac, G-DMF) use concentrated ammonia for 1 hour or AMA for 30 minutes at 60 °C. When using standard amidites (eg. C-Bz, G-iBu) use concentrated ammonia for 5 hours at 60 °C. This RNA support is compatible with deprotection chemistries used with 2’ Fluoro; 2' modified phosphoramidites and TBDMS protected reagents.

  • AMA is not recommended for sequences containing uridine bases.
