Friday Eye Candy

From the archives, here's a micrograph of a fibroblast (connective tissue cell) adherring to fibronectin coated coverslip. The cell was immunostained for regular microtubules (red) and modified detyrosinated microtubules (green, although since these are only partialy modified red+green = yellow).

Here are some strange crystals that appeared on my coverslip one day, I had just to take a picture:

very nostalgic pictures!!!

And what are these crystals? very interesting.

I never found out. They look like sodium chloride crystals, however NaCl should have disolved in the staining media ... maybe the crystals were traped in an air bubble?
