JOE is a xanthene dye, fluorescein derivative possessing two chloro- and two methoxy substituents. This fluorophore is a useful label for oligonucleotides. Its absorption and emission spectra are located between FAM and TAMRA.
The fluorophore can be introduced into oligonucleotide using this phosphoramidite. It tolerates standard ammonium deblock conditions. This product contains a pure isomer of 5-JOE dye.

Oligo synthesis details
| Diluent: | 10 % THF in acetonitrile. |
| Coupling conditions: | coupling time 6 min |
| Deprotection conditions: | Standard conditions using ammonium hydroxide; deprotection time depends on oligonucleotide composition and nucleobase protecting groups (deprotection for 17 h at 55 °С removes all protecting groups from standard nucleobases). AMA (solution of 30 % ammonium hydroxide/40 % aqueous methylamine 1:1 v/v) can be used with ~5 % of non-fluorescent side product forming. To avoid formation of the side product, start deprotection with ammonium hydroxide (30 min at RT), then add an equal volume of 40% aqueous methylamine and continue deprotection as required with AMA (e.g. 10 min at 65 °C). |
