"Photoactivation" in the Alexa488 (green emission) channel after UV illumination used for DAPI imaging

Before UV.tif	After UV.tif
1st Captured Image. Note except for 3 cells most cells are dark in the green channel.	3rd Captured Image - Note the increase in intensity of the nuclei in the green channel
Imaged widefield sequentially Ab1+TexasRed then Ab2+Alexa488 then DAPI. Single wavelength bandpass cubes. Images same gain and exposure times for each respective channel.

Well differentiated airway epithelial cells cultured on a membrane. NaK-ATPase (green) is on the basolateral membrane. Nuclei are labeled with Propidium Iodide (red). Cilia (gray) above apical membrane (light gray) are imaged using DIC. Tissue prepared and imaged on a confocal microscope by Dr. A. Livraghi, Cystic Fibrosis Center, UNC.

A live root tip of Arabidopsis. Plasma membrane labeling with FM 1-43 simultaneously scanned with DIC using a Zeiss 510 confocal microscope.	Arabidopsis guard cell labeled with GFP targeted to the membrane. Rendered with Volocity 2.6.1.	Rendered with T3D
	Please note that these images are not intended as a comparison of Volocity and T3D. Several factors including transparency and threshold are not equivalent.

	Tight Junctions are Disrupted in Epithelial Cells Expressing an Altered ZO-1 Transgene. A Madine-Darby Canine Kidney (MDCK) cell line expressing a myc-tagged ZO-1 transgene was fixed in Ethanol/Acetone and stained with antisera against the c-myc epitope tag (Cy2-green), the transmembrane protein occludin (Cy3-red), and an antiserum specific for the canine ZO-1 (Cy5-blue). The cells were imaged with a 100X PlanApo lens on the Zeiss 510 LSC Microscope using the Meta detector. Note that the transgene (red) forms large ectopic structures distinct from the normal circumferential distribution of the endogenous ZO-1 polypeptide (blue), and that the transmembrane protein occludin is also recruited into these extopic structures (green).
