RedI cut around the top end of the crystal inclusion in the image from the previous post, and erased (in photoshop) areas that allowed me to pseudocolor the objects that I could see in the lysosomal phase of this phagososome. I think the periodicity is going to be interesting with a 13-15nm round central dense area and a lucent area around that density (like a donut), still with a layer of dense protein or a trilaminar membrane.

It was fairly easy to see the repeating dots and lucent surroundings emerge as a repeating pattern along the terminal membrane at the long axis of the IPFD inclusion. IPFD crystals show for the most part a definite polarity, and any substructure in the IPFD inclusion itself is see on the butt ends of the short width axis, while a very smooth bounding area is seen on both sides running in a parallel direction.

Below, same pix as 9 13 2017 post but with a bounding box which aligns to the inset image below again.

Red dot=ribosome at 27nm diameter, purple dot=central densities, tangential end sections, 40nm dimension for a cross sectional diameter of the electron lucent area surrounding the purple dot, and 13 nm dimension is for the purple dots (some larger some smaller).
