Descriptor microsomas
Scope note: Artefactos vesiculares formados a partir del retículo endoplásmico cuando se produce rotura celular. Se aíslan mediante centrifugación diferencial y están compuestas por tres elementos estructurales: las vesículas rugosas, las vesículas lisas y los ribosomas. Numerosas actividades enzimáticas están asociadas con la fracción microsómica.

Scope note: Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction.
