Lumicks C-Trap Edge

Details of the C-Trap system.

The C-Trap system enables you to trap single molecules of DNA or proteins, manipulate them, and measure changes to their structure with high spatial and temporal resolution. Simultaneously, you can visualize a trapped construct and any interacting proteins in real time.

Optical Traps

Two independently steerable traps

Force resolution of <0.1pN with a trap stiffness of >0.35 pN/nm (1µm bead) and a maximum escape force of 500pN (4.5µm bead)
