Having completed the Protein Tethering Kit (either Cys or ybbR) service, we can keep supplying you with DNA handles and beads so that you can keep running your experiments unhindered. This is a recurring kit that provides you with materials for at least two weeks of continuous measurements.


This requires previous completion of one of the following:

Material supplied:

  • Biotin- and digoxigenin-modified DNA handles (520 bp per handle)
  • Streptavidin coated polystyrene beads (1.76 µm)
  • Anti-digoxigenin coated polystyrene beads (0.75 µm)
  • Estimated for 2 weeks of measurements
  • Estimated 1-3 weeks delivery time


Biotin-modified and digoxigenin- modified handles

One tube containing an amount of handles mix sufficient for 10 labeling reactions. Aliquot, snap freeze, and store at -80°C.

Polystyrene streptavidin beads (1.76 µm)

25 µl – 1% (w/v) (typical dilution factor 1:1000) streptavidin coated polystyrene microspheres with a diameter of 1.76 µm. Binds to biotin-modified DNA handles. Store at 4°C.

Polystyrene anti-digoxigenin beads (0.75 µm)

250 µl – 0.1% (w/v) (typical dilution factor 1:100) anti-digoxigenin coated polystyrene microspheres with a diameter of 0.75 µm. Binds  digoxigenin-modified handles. Store at 4°C.
