Live Cell Imaging tools

Chamber slides as well as cover-glass bottom plates can be used for confocal imaging.��

Fixed cell ICC can be done by growing cells on coverglass and mounting the coverglass on the slide or growing cells on the slide ()��and mounting with coverglass or any other plate or slides where live cell imaging can be done.��

Live cell imaging will however require,��cover glass chamber slide such as�� Part numbers 155409 (8 wells), 155382 (4 wells), 155379 (2 wells), and 155360 (1 well) or��cover glass bottom plate Part number P06G-1.5-14-F (6 wells), P12G-1.5-14-F (12 wells), P24G-1.5-13-F (24 wells), Cover glass bottom dish Corporation 35 mm round dishes with #1.5 coverslip bottoms: Part number P35G-1.5-14-C.

Cover Glass

All our microscopes are tuned to image optimally with No. 1.5 (~170um) coverglass, always use the No. 1.5 coverglass.

• VWR Micro Cover Glasses, No. 1.5.
• Part number (18 x 18 mm), (22 x 22 mm), (25 x 25 mm).
• Warner Instruments , No. 1.5.
• Part numbers 64-0721(22 x 22 mm), 64-0716 (22 x 30 mm), 64-0717 (22 x 40 mm).
• For High resolution Airyscan imaging use: : Part numbers 64-0732 (12 mm), 64-0733 (15 mm), 64-0734 (18 mm), and 64-0735 (25 mm).

Mounting Medium

• (Ideal for Alexa Fluor dyes),�� (Ideal for Alexa Fluor and traditional dyes, such as FITC and Cy3, and fluorescent proteins like GFP, RFP, and mCherry).
• For oil immersion objective imaging, use curing �� (Which hardens after application) or non-curing�� (Recommended for precise 3D measurements).

Mounting Media with DAPI is not recommended as it adds background to the fluorescence signal of your image.
