Iowa Black quenchers are IDT proprietary dark quenchers perfect for use in fluorescence-quenched probes. The quenchers are available as either 5'- or 3'-end modifications and provide a convenient hydrophobic handle that facilitates purification by HPLC.

These molecules absorb excitation energy from fluorophores and release it as heat. Choose your quencher based on the emission wavelength of your chosen fluorophore.
