Specifications
- Zeiss AxioObserver with 880-Quasar (34-channel spectral, high-sensitivity gallium-arsenide phosphide detectors, GaAsP) confocal module
- Airyscan FAST super-resolution (max 2x better than confocal) with zoom optics (compatible with all objective magnification) and high-speed acquisition (max 4x faster, but less than maximal resolution)
- Environmental chamber for 37°C, CO2, & humidity (35mm dishes or chamber slides)
- Definite Focus II nosepiece (fast auto-focus to compensate for focus drift during sample heating)
- NA 0.55 condenser (dry only) with DIC for 20X, 40X, 63X and 100X lenses
- Objectives:
- 10X/0.45 PlanApo (dry, no DIC)
- 20X/0.80 PlanApo, with DIC (dry)
- 40X/1.30 PlanNeofluar oil, with DIC
- 40X/1.20 C-Apo water, with DIC, upon request
- 63X/1.4 PlanApo oil, with DIC
- 100X PlanApo oil, with DIC, upon request
- 8 laser lines available:
- 405 (diode laser),
- 458, 477, 488, 514 (argon laser)
- 561 (solid-state)
- 594 (HeNe laser)
- 633 (diode laser)
- HXP 100W metal-halide illuminator for wide-field fluorescence
- Fluorescence filter sets (wide-field; non-confocal):
- Zeiss #49 for DAPI, Zeiss #38 for GFP, Zeiss #43 For Cy3
- Airyscan optical filters (vs. confocal which is fully tunable via Quasar)
- BP495-550+LP570 (dual: green & red emission)
- BP570-620+LP645 (dual: red & far-red emission)
- BP420-480+BP495-620 (dual: blue-green & green-orange)
- BP 465-505 + LP 525 (dual: blue-green & yellow-red)
- BP 420-480 + LP 605 (dual: blue & red emission)
- Zen software to control microscope and confocal
- Separate workstation for image analysis with Zen
- Download Zen LE software available for desktop computers in your lab
- Analysis with Volocity, Imaris or ImageJ on our analysis workstations
- Use LOCI BioFormats to import images into ImageJ
Advantages (over other confocals)
- Super-resolution (up to 2x better than standard confocal) for all objective magnifications with laser-scanning ease. Maximum resolution ~110nm.
- FAST module allows balancing speed with resolution (as much as 4x faster than standard Airyscan).
- Significantly less phototoxicity and photobleaching (high-sensitivity GaAsP detectors allow 10-20x less laser power for the same image quality).
Applications
- Single confocal images or image stacks for 3D viewing
- FRAP with user-defined photobleach marks
- CFP/YFP FRET
- Photoactivation at 405 nm of caged dyes and other molecules
- Colocalization of different fluorescent signals
- Speed and versatility
- Quasar “fingerprint” system separates very closely spaced fluorochromes. Example: DPPIV-GFP (Golgi, green) and Albumin-Alexa 488 (ER-Golgi, red)
