Cy5 PCR Filter Set Desription
Coligh provides professional PCR detection filter sets for PCR detection. The following four filter combinations are specially designed for Cy5 fluorescence signal detection to ensure accurate data.
- EX630/20 EM665/20 DM590 This filter set is suitable for efficient red light detection. In qPCR detection, it can detect Cy5 Alexa Fluor 647 fluorescent dyes
- EX620/16 EM665/16 DM635nm This filter set has a relatively long distance between the excitation light and the emission light. It belongs to the red light channel with low crosstalk and is suitable for qPCR and fluorescent protein markers, such as Dylight 633 and Alexa Fluor 633
- EX635/20nm EM682/20nm DM662nm is suitable for far-red fluorescent dyes, such as Alexa Fluor 647, Cy5, and DyLight 650, ensuring accurate fluorescence detection and improving experimental repeatability.
- EX640/16 EM680/16 DM662nm, suitable for far-red fluorescence detection, such as Alexa Fluor 680, IRDye 680.
These filters have the following features:
- >90% transmittance can maximize the target fluorescence signal
200-1100nm@OD>6 blocking can accurately block non-target wavelengths and effectively reduce background interference - The narrow bandwidth design of 16nm/20nm can ensure that there is no interference between different fluorescence signals, suitable for multiple fluorescence experiments of qPCR
- The use of hard coating technology can ensure that the optical performance does not decay for a long time
