Abstract
The results of a study which compared the scanning transmission electron microscope (STEM) and the backscattered electron (BSD) imaging in the scanning electron microscope (SEM) using embryonic chick tissue stained with uranyl-acetate (541093) and lead-citrate (14450603) are reported. It was determined that STEM was marginally adequate for sections of 60nm to 100nm and optimal at 200nm; however, above 200nm, resolution deteriorated and was uninformative. The BSE image was poor for sections of 60nm to 100nm and became optimal for thicknesses and 200nm and greater.
