DNA sequence to which specific proteins bind to activate or repress the expression of a gene.
Industry:Biology; Chemistry
Document that gives in a uniform manner data relating to the toxicology of a substance, its production and application, properties and methods of identification.
Note: The data sheet may also include recommendations on protective measures.
Industry:Biology; Chemistry
Dose or exposure concentration below which a defined effect will not occur.
Industry:Biology; Chemistry
Elimination that becomes concentration-independent at a concentration at which the elimination process is functioning maximally.
Industry:Biology; Chemistry
Endocytosis of a substance and its receptor following receptor binding.
Industry:Biology; Chemistry
Endonucleases which recognize specific base sequences within a DNA helix, creating a double-strand break of DNA.
Note: Type I restriction enzymes bind to these recognition sites but subsequently cut the DNA at different sites. Type II restriction enzymes both bind and cut within their recognition or target sites.
Industry:Biology; Chemistry
Enhancement of the dose-effect relationship for a poison following repeated exposure to decreasing doses.
Industry:Biology; Chemistry
Entry of a substance into the body, into an organ, into a tissue, into a cell, or into the body fluids by passage through a membrane or by other means.
Industry:Biology; Chemistry
Enzymatic antioxidant that removes the potentially toxic superoxide ion (O2- ) by disproportionating it to O2 and hydrogen peroxide (H2O2).
Industry:Biology; Chemistry
Enzymic modification of a substance by oxidation, reduction, hydrolysis, hydration, dehydrochlorination or other reactions catalysed by enzymes of the cytosol, of the endoplasmic reticulum (microsomal enzymes) or of other cell organelles.
Industry:Biology; Chemistry
