Can I use a longer oligo (longer than 60 bases) in your Antibody-Oligo kit?

In our experience, oligos up to 60 bases work best. If you use a longer oligo, we cannot guarantee success, but it should still work for you with some slight modification to the protocol. We would suggest that you allow the conjugation reaction to go overnight at 4ºC. This should improve the efficiency, which you might expect to be lower as the length of the oligo increases.
