Definition of microsome in English: microsomenoun ˈmʌɪkrəsəʊmˈmīkrəˌsōm Biology A fragment of endoplasmic reticulum and attached ribosomes obtained by the centrifugation of homogenized cells. 〔生〕微粒体 Example sentencesExamples - Intact lysosomes, mitochondria and microsomes were isolated from RPE cells.
- We attempted to circumvent the need for microsomes by attempting a coupled transcription-translation-import system using freshly purified mitochondria instead of microsomes during the translation reaction.
- These authors, by using differential and density-gradient centrifugation techniques, achieved the differentiation of the microbody fraction from lysosomes, microsomes, and mitochondria.
- The degradation of calf thymus DNA, an indicator of free iron existence, was observed in the reactions of microsomes obtained from control and baicalein-treated rats with ascorbic acid in the presence of bleomycin.
- Exposure of drug-sensitive tumor cells to doxorubicin or epirubicin results in the drugs being localized primarily within the nuclei, with much smaller amounts being localized in plasma membranes, microsomes, and the cytosol.
Derivativesadjective Biology These include cytosolic, mitochondrial, vacuolar, and particulate forms, with the particulate forms being further subdivided into those present in microsomal membranes, plasma membranes, and lipid bodies. Example sentencesExamples - Tests were performed with and without metabolic activation by the microsomal mixed function oxidase system.
- Protein was determined in both microsomal and cytosolic fractions using the Lowry procedure.
- Nevertheless, slight increases in the sister chromatid exchanges frequencies have been found mainly in the absence of the S9 microsomal fraction in the in vitro assays.
- It was present in the cytosolic as well as microsomal fractions, and assays with a series of substrates indicated that the enzymes in the each compartment had a different specificity.
