Dark Quencher CPG

Dark Quencher CPG


Dark Quencher-534 Phosphoramidites & Dark Quencher-579 Phosphoramidites are a non-fluorescent chromophore, and extensively used as the 3'-quencher moiety in a variety of FRET (Fluorescence Resonance Energy Transfer) in DNA detection probes. Such probes are primarily used in nucleic acid assays.

Advantages:

The advantages of using a Dark Quencher in a FRET probe are

  • Low background fluorescence & higher dynamic range,
  • Responsiveness to multiplex assays - because of a dark quencher having no secondary fluorescence.
  • Comfort of synthesis of FRET probes with a Dark Quencher - because dark quenchers being resistant to degradation throughout the oligo deprotection step.

Storage and handling:
Shipping conditions: Cold Box Storage conditions: -15 to -30 °C, Light sensitive material.
