| Edridge-Green lamp | A lantern used to test recognition of coloured signals; it displays a single light with colour filters in rotating disks that can be modified to simulate conditions of weather and atmosphere. This test for colour blindness was officially adopted in Great Britain in 1915 in place of the Holmgren wool test, but is now seldom used. (05 Mar 2000) |
| ethyl green | The sulfate of di-(p-diethylamino)-triphenyl carbinolanhydride. An indicator dye that changes from yellow to green at pH 0.0 to 2.6; also used as a topical antiseptic and as a selective bacteriostatic agent in culture media. Synonym: ethyl green. (05 Mar 2000) |
| Janus green B | C30H31N6Cl; diethylsafraninazodimethylaniline chloride;a basic dye used in histology and to stain mitochondria supravitally. (05 Mar 2000) |
| fast green FCF | An acid arylmethane dye widely used in histology and cytology and less subject to fading than light green FCF which it has replaced in many procedures; used as a quantitative cytochemical stain for histones at alkaline pH after acid extraction of DNA, and also in electrophoresis as a protein stain. (05 Mar 2000) |
| light green SF yellowish | An acid arylmethane dye, used as a cytoplasmic stain in plant and animal histology; fades badly in bright light. (05 Mar 2000) |
