I want to use a cleavable 4FB linker with your antibody-oligo kit. Which is the cleavable linker?

If you use the Ab-oligo kit, this comes with the S-4FB crosslinker. Instead of using the crosslinker in the kit, you may use an alternative 4FB crosslinker to attach to your oligo, the S-SS-4FB crosslinker (Cat. No. S-1037). The Excel spreadsheet that comes with the kit (the calculator) can tell you how much of the reagent to use once resuspended. You would then be able to cleave the Ab-oligo linkage, which is a disulfide bond.
