There are three core laboratories on campus that offer expertise, instruction, and instrumentation in optical microscopy for research.

• The CNR Biological Imaging Facility (This lab): Confocal, deconvolution, and widefield fluorescence microscopy, live-cell imaging, microtechnique, training in digital image processing and analysis. Located in 381 Koshland Hall
  
  
• Molecular Imaging Center: Multi-photon laser scanning confocal microscopy, electrophysiology, live-cell imaging. Located in LSA and LKS.
  
  
• Electron Microscopy Laboratory: Transmission and scanning electron microscopy. Located in Giannini Hall.
  
  
• CIRM/QB3 Shared Stem Cell Facility: Available for the study of stem cells. Located in Stanley Hall
  
  
• Core Facilities on the Berkeley campus.
  
  
• The Golub Microscope Collection: Web site dedicated to Dr. Orville J. Golub's collection of antique microscopes from the 17th–20th Centuries. The collection is located in VLSB
  

Golovinomyces orontii (powdery mildew fungus) infection of Arabidopsis thaliana leaf. After infection, the G. orontii conidium (C) germinated and grew hyphae on the leaf surface. Infected leaf was stained with DAPI (nucleic acid stain) to quantify DNA content of A. thaliana mesophyll cells underlying the fungal feeding structure (haustorium, H) embedded in the leaf epidermis. To determine the DNA content of mesophyll nuclei, fluorescence intensity sum was measured (large gray spheres) and normalized to guard cell nuclei (small grey spheres around stomata opening) as they have a 2C DNA content.  Z-stack was taken with the Zeiss LSM710 and fluorescence intensity sum was measured with Spots application in Imaris v9.
