PALM MicroBeam
Laser microdissection and pressure catapulting microscope from Carl Zeiss
The PALM MicroBeam microscope from Carl Zeiss is a Laser Microdissection and Pressure Catapulting (LMPC) system.
It was purchased using a grant from the Swedish Research Council and the main applicant, Prof. Marianne Quiding-Järbrink at the Dept of Microbiology and Immunology, kindly placed it at the CCI in 2008.
Microscope
This laser microdissection system is based on a fully motorized inverted microscope, the AxioObserver Z1, equipped with a RoboMover collector control unit, a pulsed 355 nm laser for cutting and two different cameras: an AxioCam ICc1, a color camera for bright field imaging, and an AxioCam MRm, a black and white camera for fluorescence imaging. The microscope is controlled by the PALM RoboSoftware.
Fluorecsence filters
For fluorescence imaging there is a Colibri illumination module, with light emitting diodes (LEDs) giving three different excitation wavelengths: 365 nm, 470 nm and 585 nm, and a triple filter (Filter set 62 HE BFP GFP HcRed shift free) for fluorescence imaging. The triple filter has the emission bandwidths 402 – 448 nm, 500 - 554 nm, and > 615 nm for blue, green and red fluorescence.
