Organism which does not require dioxygen for life.
Note: Obligate (strict) anaerobes grow only in the absence of dioxygen. Facultative anaerobes can grow either in the presence or in the absence of dioxygen.
Industry:Biology; Chemistry
Protein (immunoglobulin) produced by the immune system in response to exposure to an antigenic molecule and characterized by its specific binding to a site on that molecule (antigenic determinant or epitope).
Industry:Biology; Chemistry
Linking of the complementary pair of polynucleotide chains of nucleic acids by means of hydrogen bonds between complementary purine and pyrimidine bases, adenine with thymine or uracil, cytosine with guanine.
Industry:Biology; Chemistry
For a substance the time required for the amount of that substance in a biological system to be reduced to one half of its value by biological processes, when the rate of removal is approximately exponential.
Industry:Biology; Chemistry
One of several alternate forms of a gene which occur at the same relative position (locus) on homologous chromosomes and which become separated during meiosis and can be recombined following fusion of gametes.
Industry:Biology; Chemistry
Compound that contains a temporary linkage between a given active substance and a transient carrier group, the latter producing improved physicochemical or pharmacokinetic properties and easily removable in vivo.
Industry:Biology; Chemistry
Compound that contains a temporary linkage between a given active substance and a transient carrier group, the latter producing improved physicochemical or pharmacokinetic properties and easily removable in vivo.
Industry:Biology; Chemistry
Practical certainty that there will be no exposure of organisms to toxic amounts of any substance or group of substances: this implies attaining an acceptably low risk of exposure to potentially toxic substances.
Industry:Biology; Chemistry
Control (individual or group or case) selected to be similar to a study individual or group, or case, in specific characteristics: some commonly used matching variables are age, sex, race and socio-economic status.
Industry:Biology; Chemistry
Substance or a structural part (epitope) of a substance which causes the immune system to produce specific antibody or specific cells and which combines with specific binding sites (epitopes) on the antibody or cells.
