A simplified method of preparation of mammalian intestine samples for scanning electron microscopy

Abstract: Due to strong tissue hydration and complex architecture of the mucous membrane, appropriate preparation of inhomogeneous gastrointestinal tissues, especially from the intestine, for scanning electron microscopy is still a challenge and requires constant improvement of preparation techniques. In this article, we describe a simplified method of preparation of small intestinal mucosa tissues for observations in a scanning electron microscope. We emphasized the most important points in the preparation process that… Show more

“…The samples were cut into 10 mm‐length pieces and post‐fixed in osmium tetroxide (1%) for 24 h. Then, the specimens were dehydrated through ascending concentrations of ethanol (10%, 30%, 50%, 70%, 100%), acetone/ethanol (50%, 50%), and pure acetone (100%) (Skrzypek & Kazimierczak, 2018). Afterward, drying was done by a critical point dryer (Critical Point Dryer K850, Emitech), and specimens were coated with a layer of gold using a sputtering device (Sputter Coater S 150B, Edwards).…”

“…The sample was divided into cardiac, fundic, body and antropyloric regions. The specimens were dehydrated in ascending concentrations of ethanol; 10%, 30%, 50%, 70% and 100 (3-5 min in each change) and twice in acetone (50%-50%; absolute ethanol/acetone and pure acetone) (Skrzypek & Kazimierczak, 2018). Then, secondary fixation was performed in 1% osmium tetroxide, drying in critical point dryer and coated with gold.…”
