There are two options we can suggest for FRET pair of dyes from our catalog list.

*Cyanine3 (donor) and Cyanine5 (acceptor) can be as FRET pair of dyes:

We do have different functionalized Cyanine3 and Cyanine5 derivatives:

Cyanine3 - 

Sulfo-Cyanine3 - 

Cyanine5 - 

Sulfo-Cyanine5 - 

*Coumarin 343 (donor) and FAM (acceptor). Coumarin 343 forms a FRET pair with fluorescein, and can harvest blue light energy for the subsequent transfer to other fluorophores: 

Below are the derivatives for these products:

Coumarin 343 - 

FAM -   

*BDP FL may be quenched by azo quenchers like Dabcyl, and by FRET acceptors like BDP TMR:



TAMRA can be used with FAM as FRET pair.
