Fluorescent Dyes & Stains
BioSciences
Rhodamine B isothiocyanate, mixture of isomers [36877-69-7] U5g ...............
MW 536.1
Fluorescent marker for proteins. Also used as a counterstain in conjunction with FITC.
J. Bacteriol., 83, 1358 (1962); Arch. Biochem. Biophys., 133, 263 (1969)
Rhodamine WT, 5% aqueous solution H4g ....................................
Exc max: 554nm Emiss max: 579nm Water leak tracing dye.
TB Fluorostain Kit ..........................................................
Fluorochrome staining of mycobacteria in an acid-fast smear offers several
advantages over traditional carbol-fuchsin methods. Lower magnification
is required; fluorescent mycobacteria stand out brightly on a darkened
background. Smaller numbers of mycobacteria are easily identified with a
fluorescent stain. Technical Data Sheet #488
Kit contains: 525ml of Staining Solution A, 500ml of Acid Solution B and
500ml Counterstaining Solution C
Features:
• 100 tests per kit
• less than 12 minutes to perform staining
• microwave method reduces time and enhances results
• much less Auramine O and Rhodamine B used, reducing costs and hazards
• faster, better counterstain
Thiazole orange [107091-89-4] H6gk ..........................................
MW 476.32 mp 270° (dec.) l max 512nm
Fluorescent dye for reticulocyte analysis. Also useful for Plasmodium species analysis.
Cytometry, 7, 508 (1986); 8, 568 (1987); Angew. Chem., 111, 2340-2343, (1999); Agnew. Chem. Int. Ed., 38, 2203-2206, (1999)
Uvitex ® 2B [27344-41-8] BH6g ................................................
Excitation Max: 350nm TSCA
Uvitex 2B fluorescent dye will bind to the chitin in fungal walls and is highly
selective for fungi and algae in tissue sections. It has a slower fade rate than
more commonly used fungal fluorescent dyes. C.I. Fluorescent Brightener 362;
Derivative of stilbene disulfonic acid. Lab. Med., 18, 603 (1987)
