Cy5.5 Filter Set For PCR
Cy5.5 filter set is a high performance fluorescence filter set specially designed for far-red fluorescent dye Cy5.5. Coligh manufactures high quality hard coating interference filter set for PCR application
We provide two filter sets of filter sets for Cy5.5 detection.
- Set 1: EX675/20nm EM725/40nm DM702nm
- Set 2: EX682/20nm EM725/40nm DM702nm
- Cut-off depth: 200-1100nm@OD>6, reduce autofluorescence and improve data reliability
- Transmittance>90%, maximize fluorescence signal transmission
- High steepness filter design to reduce interference from non-target wavelengths
Cy5.5 Filter Set for PCR Description
COligh provides two filter sets for Cy5.5 fluorescence detection, which accurately cover the excitation and emission spectra of Cy5.5 (excitation spectrum 675-682nm emission spectrum 710-750nm), ensuring high sensitivity of fluorescence signal detection
- Set 1 (EX675/20 – EM725/40 – DM702)
- Set 2 (EX682/20 – EM725/40 – DM702)
Both can improve the excitation efficiency of Cy5.5 dye and optimize the quality of far-red fluorescence signal
In these optical filter sets, the transmittance of the filter is >90%, and the ultra-strong cutoff depth of 200-1100nm@OD>6 can block the interference of background light, maximize the transmission of fluorescence signal, and improve the reliability of data. Before the production of the filter, we design high-steepness filtering to improve the purity of the target fluorescence signal.
In addition, we use hard coating technology, which can be corrosion-resistant and high-temperature-resistant and can be used for a long time
