DNA constructs and kits to tether dsDNA, ssDNA, or any sequence of interest in the canonical dumbbell configuration. Connect with us for protein folding solutions →
17.9 kb DNA with two nicks 5 kb apart. Stretch it to open a 5 kb ssDNA gap between two dsDNA arms.
One Atto dye marks the gap junction: L = 3' end or R = 5' end.
Fluorophore: L – Atto647N · R – Atto565, both in stock for next-day shipment
Other dye? Ask for your fluorophore of choice →
Per vial: ≥ 20 C-Trap runs
$450
Two biotinylated handles. Ligate any dsDNA insert between them (Golden Gate compatible).
An optional Atto dye on Handle L or R (7 bp from the overhang) marks the tether direction.
Fluorophore: no dye · L – Atto647N · R – Atto565, all in stock
Other dye? Ask for your fluorophore of choice →
Per kit: 8 reactions (up to 40 C-Trap runs)
$350 no dye · $390 with dye
Handles with long overhangs. Anneal and ligate your ssDNA or RNA oligo.
In stock
Per kit: 5 reactions (25 C-Trap runs)
$350
48.5 kb lambda DNA with 3× biotin at each end, for tethering between two streptavidin beads.
Fluorophore: none
Per vial: 25 µl (20–30 C-Trap runs)
$190
These constructs are the start of a growing catalogue, and we are building it with you.
