Calcein
MP BiomedicalsCalcein is an indicator for the determination of calcium by titration with EDTA. The excitation wavelength and emission wavelength are 495/515 nm. It is suitable for fluorometric determination of calcium. It does not fluoresce in strong alkaline solution, but an intense fluorescence appears in the…

Brilliant Sulfaflavine
MP BiomedicalsBrilliant Sulfaflavine is not the same as FIAT (Brilliant Sulfoflavin FF; Acid Yellow 7) which has only one methyl group para to the nitrogen. Brilliant sulfaflavine was used as fluorescent tracers to study the application rate of foliar fungicides when applied to soybeans for the control of rust.

Azomethine H Monosodium Salt Monohydrate
MP BiomedicalsAzomethine H is a reagent for the determination of boron in soil, plants, composts, manure, water and nutrient solutions.
-
Sulforhodamine B
MP BiomedicalsSulforhodamine B is a fluorescent dye. Sulforhodamine B can be used as a protein tag - by sulfamido condensation with a proteinaceous substrate containing a primary amine function. Sulforhodamine B will fluoresce red. Because of its red fluorescence it can be used in conjuction with fluorescein…

Primulin
MP BiomedicalsPrimuline is a dye containing the benzothiazole ring system. The primulines are considered derivatives of dehydrothiotoluidine (aminobenzenyltoluylmercaptan). It is pale yellow in solution under visible light and is blue fluorescent under ultraviolet. Primulin is used in retrograde double…
-
Fluorescamine
MP BiomedicalsFluorescamine is a non-fluorescent reagent that reacts readily with primary amino groups in amino acids and peptides to form highly fluorescent derivatives, whereas the reagent and its degradation products are non-fluorescent. No significant fluorescence with ammonia. Low background due to…
