Studies on Bioluminescence
1. Small dumps of the luminous cells of Mnemiopsis cannot readily be stimulated mechanically but will luminesce on treatment with saponin solution. Larger groups of luminous cells (such as are connected with two paddle plates) luminesce on mechanical stimulation. This suggests that mechanical stimulation to luminesce occurs chiefly through a nerve mechanism which has been broken up in the small...
متن کاملStudies on Bioluminescence
Some solubility, oxidation, reduction, and compound-forming characteristics of extracts of Cypridina luciferin have been presented. A method of purification has been described which increased the amount of luciferin per unit of dry weight, as measured by the total light emitted, to about two thousand times that in the dry starting material. The best yields were from 50 to 65 per cent.
متن کاملStudies on the Bioluminescence of Renilla reniformis*
In earlier investigations on the bioluminescent system of the sea pansy, Renilla renifformis, we reported that adenine-containing nucleotides (either adenosine mono-, di-, or triphosphate), an oxidizable substrate (Renilla luciferin), molecular oxygen, and an enzyme (RenilZa luciferase) were required for luminescence in crude extracts of this organism (1, 2). In addition, several lines of evide...
متن کاملPredicting Bioluminescence Signatures Based on the NAVOCEANO Bioluminescence Database
Bioluminescence represents an operational threat to U.S. Navy nighttime operations because of the risk due to flow-stimulated light emission from naturally occurring plankton. Conversely, bioluminescence presents additional capabilities for detecting moving objects at night, particularly in the littoral zone where conventional acoustic surveillance is severely challenged. We are interested in t...
متن کاملIn vivo mouse studies with bioluminescence tomography.
Bioluminescence tomography (BLT) is a new molecular imaging mode, which is being actively developed to reveal molecular and cellular signatures as labeled by bioluminescent probes in a living small animal. This technology can help diagnose diseases, evaluate therapies, and facilitate drug development with mouse models. In this paper, we describe in vivo mouse experiments with BLT, and propose t...
