Re: Endoplasmic reticulum visible with phase contrast?

I had never heard of microplicae before, but after surfing the internet I agree with you. The structure is similar to that of the inner membrane of the mitochondria, with different functions depending on the type of cell where they are found

Re: Endoplasmic reticulum visible with phase contrast?

I think reticulum only can be seen under electron microscope. The areas where some strangers lines appear seems to be folded parts of the own cell. The part of the cell without foldings has not these structures. ER only is 7 nm width

PZO Warszawa binocular

This is my amazing microscope :roll: It is a bit old (1977), but Polish engineers worked well. I bought It for 60 € (second hand). The eyepieces are x12 and the objetives are x5, X10, x40 and x100 (oil). I had to adjust some things but It works fine. In some years I will buy another trinocular to be...
