| acidic dyes | Dye's which ionise in solution to produce negatively charged ions or anions; they consist of sodium salts of phenols and carboxylic acid dyes; their solutions tend to be neutral or slightly alkaline; examples are eosin and aniline blue. (05 Mar 2000) |

| acidic amino acid | An Amino acid with a second acid moiety, e.g., glutamic acid, aspartic acid, cysteic acid. (05 Mar 2000) |
| acidic anhydride | <chemistry> A substance (such as the oxide of a nonmetallic element) that will react with water to form an acid. (09 Oct 1997) |
| glial fibrillary acidic protein | <protein> This protein, found in microfilaments of glial cells, helps distinguish glial from nonglial tumours. A laboratory stain is used to test for its presence. (16 Dec 1997) |
| Myxococcus acidic endoprotease | <enzyme> From myxococcus xanthus; cleaves phe-met bond of kappa-casein at pH 5.9; 12 kD; amino acid sequence given in first source Registry number: EC 3.4.99.- Synonym: maep (26 Jun 1999) |
| N-acetylated-alpha-linked acidic dipeptidase | <enzyme> Chloride-dependent membrane bound metallopeptidase, most active with the endogenous neuropeptide n-acetyl-l-aspartyl-l-glutamate Registry number: EC 3.4.13.- Synonym: naaladase, glutamate carboxypeptidase II, prostate-specific membrane antigen, psm antigen (26 Jun 1999) |
| fibroblast growth factor, acidic | <chemical> A growth factor which has been isolated from a variety of cells. It contains 154 amino acid residues and has potent heparin-binding activity. Heparin potentiates the biological activities of afgf. The growth factor is an extremely potent inducer of DNA synthesis in a variety of normal diploid mammalian cell types from mesoderm and neuroectoderm lineages and also has chemotactic and mitogenic activities. Chemical name: Fibroblast growth factor (human brain acidic protein moiety reduced) (12 Dec 1998) |
| acridine dyes | Derivatives of the compound acridine which is closely related to xanthene; important as fluorochromes in histology, cytochemistry, and chemotherapy; examples include acriflavine, acridine orange, and quinacrine mustard. (05 Mar 2000) |
| azin dyes | Dye derivatives of phenazine, C6H4-N2-C6H4 that include important histologic stains, such as neutral red, azocarmine G., and safranin O. (05 Mar 2000) |
| azocarmine dyes | Dye's giving a dark purplish red colour as histologic stains. (05 Mar 2000) |
| azo dyes | Dye's in which the azo group is the chromophore and joins benzene or naphthalene rings; they include a large number of biologic stains, such as Congo red and oil red O; also used clinically to promote epithelial growth in the treatment of ulcers, burns, and other wounds; many have anticoagulant action. (05 Mar 2000) |
| basic dyes | Dye's which ionise in solution to give positively charged ions or cations; the auxochrome group is an amine which can form a salt with an acid like HCl; solutions are usually slightly acidic; examples include basic fuchsin and toluidine blue O. (05 Mar 2000) |
| chlorotriazine dyes | Dyes containing one or more chlorotriazine moieties that react with polysaccharides. (05 Mar 2000) |
| rosanilin dyes | Several triaminotriphenylmethane dye's or mixtures of them often sold under the name of basic fuchsin; rosanilin dye's differ from other triphenylmethane dye's in that the amino groups are unsubstituted, and they may have methyl groups introduced directly onto the benzene rings; the four possible such dyes are pararosanilin, rosanilin, new fuchsin, and magenta II. (05 Mar 2000) |
| rosaniline dyes | Any dye or mixture of dyes made from rosaniline, a red triphenylmethane aniline derivative; used to colour fabrics, paper and as biological stain; also used as disinfectant and topical antifungal agent. (12 Dec 1998) |
