Laser Microdissection

Microdissection allows one to select and isolate part of a sample and use it for further studies (RT-PCR, protein analysis, selection of live cells). Laser microdissection can also be used with live samples to study recovery after a cut, protein recruitment after photodamage… The system is paired with optical tweezer to manipulate samples.

This widefield microscope is equipped with:

  • 3 sets of filters for imaging (Blue/Green/Red)
  • a laser microdissection unit - dissection and recovery of cells or subcellular compartments,
  • optical tweezers - mechanical manipulation of cells or samples without contact by using an infra-red laser,
  • an incubator for live cell imaging (time lapse).
