18327_78174_mouse#2 day 21 from_Glutamate-cysteine ligase catalytic subunit  h/h mouse given NAC. Fixation was in modified Karnovskys.  Isolated mitochondria. Condensed cristi. Some microsomes as well.  Typical mitochondria is about 200 nm in the smallest diameter. Original mag is likely to be about 40,000 (I will check) after 4 x magnification in enlargement. (which is useless, since i need a micron marker). Ref for specifics of the animal (h/h) are found in this article.
