| BHQ®-2 T-Linker 500Å CPG is used to add the non-fluorescent quencher (BHQ-2) to the 3' end of an oligonucleotide. BHQ-2 quencher has maximal absorption in the 560 to 670 nm range, which provides excellent quenching of fluorophores emitting in this range, such as TAMRA, Cy3, and CAL Fluor® Red 610. The BHQ-2 T-Linker Arm CPG has a 3' phosphate followed by a glycolate linkage to the CPG support, which allows for rapid cleavage of the oligo from the support and is labile enough for base-sensitive oligonucleotides. The 500 Å CPG is useful for the synthesis of oligos up to 50-mers in length, especially when larger amounts of product are desired, as it allows for greater nucleoside loading amounts than do supports with larger pore sizes. |

Cleavage conditions: When using fast deprotecting amidites use concentrated Ammonia for 20 min at 25 °C or Ammonia/ Methylamine (AMA) (1:1)for 5 min at 25 °C; or
t-butylamine/H2O(1:3) for 45 min at 25 °C (TAMRA requires deprotection with TBA). When using standard amidites (eg. C-Bz, G-iBu) use concentrated Ammonia for 20 min at 25 °C.Deprotection conditions: When using fast deprotecting amidites (eg. C-Ac, G-DMF) deprotect in concentrated ammonia for 1 hour or AMA for 30 minutes at 60 °C. When using standard amidites (eg. C-Bz, G-iBu) deprotect in concentrated ammonia for 5 hours at 60 °C. If you are using base sensitive fluorophores (ie. TAMRA) we recommend deprotecting the oligonucleotide in t-butylamine/H2O(1:3) for 6 hours at 60 °C. The mass this product adds after conjugation and work-up (the additional mass seen by mass spectrometry) is:1100.96 |
