Since the request structure is failing...

Term: rhodamineFluorescence

Name: Rhodamine Fluorescence

Definition: The concentration of Rhodamine dye, usually measure using florescence. The rhodamines are xanthene derivatives structurally related to fluorescein. Important members of the rhodamine family are Rhodamine 6G, Rhodamine 123, and Rhodamine B. Water soluble Rhodamine WT is used in water tracing work.

And another for Phycoerythrin

Term: phycoerythrin

Name: Phycoerythrin

Definition: Phycoerythrin is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in red algae and cryptophytes, accessory to the main chlorophyll pigments responsible for photosynthesis. Phycoerythrin concentrations can be used as a proxy measurement for marine cyanobacteria.

Term: opticalBrighteners

Name: Optical Brighteners

Definition: Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence. These additives are often used to enhance the appearance of color of fabric and paper, causing a "whitening" effect; they make intrinsically yellow/orange materials look less so, by compensating the deficit in blue and purple light reflected by the material, with the blue and purple optical emission of the fluorophore. Optical brightener concentrations may be measured during wastewater monitoring.

Term: ptsa

Name: PTSA

Definition: 1,3,6,8-Pyrenetetrasulfonic acid tetrasodium salt hydrate is a fluorescent probe and pH indicator. It fluoresces blue in acidic solutions and in acidic organelles but fluoresces green in more basic organelles. This compound is potentially useful as a coloring agent, biological stain, optical detecting reagent.

Term: btex

Name: BTEX

Definition: In the petroleum refining and petrochemical industries, the initialism BTEX refers to mixtures of benzene, toluene, ethylbenzene, and the three xylene isomers, all of which are aromatic hydrocarbons. The ethylbenzene may be excluded, in which case the term BTX is used.

Term: tryptophan

Name: Tryptophan

Definition: Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning that the body cannot synthesize it and it must be obtained from the diet. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. It is encoded by the codon UGG.
