| site-specific DNA-methyltransferase (adenine-specific) | <enzyme> An enzyme responsible for producing a species-characteristic methylation pattern on adenine residues in a specific short base sequence in the host cell DNA. The enzyme catalyses the methylation of DNA adenine in the presence of s-adenosyl-l-methionine to form DNA containing 6-methylaminopurine and s-adenosyl-l-homocysteine. Registry number: EC 2.1.1.72 (12 Dec 1998) |

| site-specific DNA methyltransferase (cytosine-specific) | <enzyme> An enzyme responsible for producing a species-characteristic methylation pattern on cytosine residues in a specific short base sequence in the host cell's DNA. The enzyme catalyses the methylation of DNA cytosine in the presence of s-adenosyl-l-methionine to form s-adenosyl-l-homocysteine and DNA containing 5-methylcytosine. Registry number: EC 2.1.1.73 (12 Dec 1998) |
| antiserum | <haematology, immunology> Serum containing immunoglobulins against specified antigens. (13 Jan 1998) |
| antiserum anaphylaxis | A reaction resulting from inoculation of antigen in an animal previously inoculated intravenously with specific antiserum from another animal, a latent period being required between the two inoculations. Synonym: antiserum anaphylaxis. (05 Mar 2000) |
| monovalent antiserum | See: antiserum. (05 Mar 2000) |
| polyclonal antiserum | A mixture of antibodies to a variety of antigens or to a variety of determinants on a single antigen. (09 Oct 1997) |
| polyvalent antiserum | See: antiserum. (05 Mar 2000) |
| heterologous antiserum | An antiserum that reacts with (e.g., agglutinates) certain microorganisms or other complexes of antigens, even though the antiserum was produced by means of stimulation with a different microorganism or antigenic material. See: homologous antiserum. (05 Mar 2000) |
| homologous antiserum | An antiserum in which there is complete correspondence between the content of antibodies and the antigenic material used for producing the antiserum. (05 Mar 2000) |
| nerve growth factor antiserum | An antiserum containing antibodies against nerve growth factor; when injected into newborn animals the majority of sympathetic ganglion cells are permanently destroyed, resulting in hypoinnervation of peripheral tissues. Synonym: NGF antiserum. (05 Mar 2000) |
| NGF antiserum | An antiserum containing antibodies against nerve growth factor; when injected into newborn animals the majority of sympathetic ganglion cells are permanently destroyed, resulting in hypoinnervation of peripheral tissues. Synonym: NGF antiserum. (05 Mar 2000) |
| age-specific rate | A rate for a specified age group, in which the numerator and denominator refer to the same age group. (05 Mar 2000) |
| Bensley's specific granules | Granule's in the cells of the islands of Langerhans in the pancreas. (05 Mar 2000) |
| brain-specific kinase | <enzyme> Expressed specifically in brain; member of the eph/elk receptor-like kinase family; mw 105 kD; may represent murine homolog of chicken cek7 receptor-like kinase; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: bsk tyrosine kinase (26 Jun 1999) |
| galactosyl-1-3-N-acetylgalactosaminyl-specific 2,6-sialyltransferase | <enzyme> Genbank x77775 Registry number: EC 2.4.99.- Synonym: galbeta1,3galnac 2,6-sialyltransferase, st6galnac II (26 Jun 1999) |
