Overview

Manufacturer: Zeiss, PALM

The laser capture microscope uses a UV laser to first microdissect tissue sections and then catapult the dissected piece of tissue into an Eppendorf tube. The UV wavelength of the laser is too long to damage polynucleotides. The same system is also fitted with an infra-red laser that acts as optical tweezers for the manipulationof single cells and smallparticles. The system is fitted to a Zeiss inverted fluorescence microscope

Benefits of the PALM laser microdissection

Perform genomic, qPCR or proteomics analysis on specific regions of tissue.
