Catalog Number: 10-5913-xx
Description: Cy3™ Phosphoramidite
| 1-[3-(4-monomethoxytrityloxy)propyl]-1'-[3-[(2-cyanoethyl)-(N,N-diisopropyl) phosphoramidityl]propyl]-3,3,3',3'-tetramethylindocarbocyanine chloride | ||
| Formula: C58H70N4O4PCl | M.W.: 953.64 | F.W.: 507.59 |
Diluent: Anhydrous Acetonitrile |
| Coupling: 3 minute coupling time recommended. Use 0.02M Iodine to avoid degradation of the cyanine dye. |
| Deprotection: If dmf-dG is used during synthesis, deprotect in Ammonium Hydroxide for 2 hours at 65 °C; with ibu-dG, deprotect for 24-36 hours at room temperature. Note Cy3 is compatible with UltraFast deprotection (AMA 10 minutes at 65 °C) if Ac-dC was used. Technical Bulletin |
| Storage: Freezer storage, -10 to -30°C, dry |
| Stability in Solution: 2-3 days |

QUESTION: What are the relative extinction coefficients of various dyes?
RESPONSE:Please see http://www.glenres.com/Technical/Extinctions.html#dyes
QUESTION: Does AMA or methylamine cause any degradation to fluorescein or fluorescein-type dyes such as FAM or FITC?
RESPONSE:Response: While AMA (Ammonium hydroxide/40% Methylamine 1:1 v/v) is considered compatible with fluorescein, the use of methylamine when deprotecting a Fluorescein-labeled oligo does lead to a small amount of degradation, which is characterized by a the appearance of a late-eluting peak by RP HPLC that shows no visible fluorescein absorbance. With standard deprotection conditions (AMA 10 minutes at 65 C) the amount of degradation is approximately 5%. The impurity is not detected with AMA at RT for 2 hours.
