WebNov 7, 2024 · In vitro comes from the Latin term "in glass." The term refers to studies of biological properties that are done in a test tube (i.e. in a glass vessel) rather than in a … WebAbstract. A key step in the skin sensitization process is the formation of a covalent adduct between the skin sensitizer and endogenous proteins and/or peptides in the skin. A published peptide depletion assay was used to relate the in vitro reactivity of fragrance molecules to LLNA data. Using the classical assay, 22 of 28 tested moderate to ...

WebFollowing incubation, the monolayers are then microscopically examined, and the cell layer reactivity is scored for any abnormal cell morphology and cellular degeneration. Cells are scored for reactivity at 24–48 h on a grading scale: 0 = no reactivity, 1 = slight, 2 = mild, 3 = moderate, 4 = severe reactivity. In vitro (meaning in glass, or in the glass) studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates.
