  • Appearance: White Powder
  • Extinction Coefficient at 260 nm: 12010

Product usage:

  • Cleavage conditions: Use concentrated ammonia for 90 minutes at 25° C or 1:1 ammonia:methylamine (AMA) for 25 minutes at 25° C.
  • Deprotection conditions: When using fast deprotecting amidites (eg. C-Ac, G-DMF, G-PAC) 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.
  • ABI 3900 users: Columns should be compatible with standard ABI protocols. However, when using 50 nmol Super Columns, the following changes are recommended: 1) Change the head pressure/purge pressure/chamber pressure to 3.5 psi.2) An additional oxidation step3) OPTIONAL (but may help): extension of the coupling time to 20 secImage of cleaved and deprotected structure:
  • The mass this product adds after conjugation and work-up (the additional mass seen by mass spectrometry) is: 329.2

Storage and handling:

  • Shipping conditions: Ambient
  • Storage conditions: +2 to +8 °C in sealed container
