Glen Research now has disposable columns suitable for use in a variety of DNA synthesizers, including ABI and Vega instruments. Columns are available in 5ooA (0.2, 1.0, and 10 μmole synthesis scale) and 1000A (0.2 μmole synthesis scale) CPG for the synthesis of intermediate (80-mer) sequences, respectively.
We also now have available an alternative activator for use in DNA synthesis: 4-nitrophenyltetrazole. This product appears to be a more efficient activator than tetrazole.
