NanoTracker fluorescent DNA Manipulation from JPK
This video shows the JPK Instruments' NanoTracker optical tweezers platform is used for the versatile manipulation of single biomolecules, simultaneous to sensitive fluorescence microscopy in a JPK's microfluidics flow cell. The non-fluorescent DNA is held between two optically trapped beads.
The fluorescent fluid is applied using a multichannel laminar flow cell. The trap-held DNA molecule is suspended successively in a plain buffer and the DNA molecules, coated with fluorescent proteins that specifically bind to the DNA.
