Fluorescence detection in living cells and ways to improve your image

By on December 9, 2013

Fluorescence imaging of living cells can provide important data regarding the function and localization of proteins and other bio-molecules within a cell or tissue.

These images give insight into fundamentally important biological processes and improve our knowledge about transient interactions we might not be able to detect otherwise.  An added benefit is some simply remarkable pictures of colorized cells which are just fun to look at.  Although in theory, fluorescence microscopy is simple, obtaining suitable images is difficult.  Problems with cell health can occur due to long incubations in D-PBS in an attempt to reduce auto-fluorescence.  Cell death due to light intensity or photo-bleaching can be problematic and need to be overcome.  If you are having problems with signal:noise  or cell health or obtaining the best image possible now is your chance to ask the expert.
