Prefer to order through purchase order? Request a quote at the checkout page.

Having completed the Protein tethering kits (cysteine or ybbR), we can keep supplying you with DNA handles and beads so that you can keep running experiments. This kit is a recurring product that provides you with materials for at least two weeks of continuous measurements.


This kit requires the 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 measurement
  • 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.
