Histology Reagents
Biotium EOSIN-5-Maleimide
Eosin-5-maleimide is a good photosensitizer and can be used to selectively label thiols. It has a quantum yield of 0.57 for singlet oxygen generation, which makes it useful for photoconversion of electron-rich materials such as diaminobenzidine (DAB) or fluorescent dyes into highly electron-dense materials for high resolution electron microscopy studies. Additionally, eosin is a good fluorescence acceptor for fluorescein (FAM), dansyl and coumarin dyes in fluorescence resonance energy transfer (FRET). Properties: Ex/Em (MeOH) = 524/545 nm; e = 100,000; Orange solid soluble in DMF or DMSO; Store at -20°C and protect from light; C24H9Br4NO7; MW: 742.95.
Electron Microscopy Sciences Glutaraldehyde 25% Aqueous Solution, 111-30-8, MFCD00007025, 10 mL ampoule
Formula: OCHCH2CH2CH2CHO, MW: 100.12. After glutaraldehyde has been purified to EM grade, it has a high risk of polymerizing if it is not handled properly. Electron Microscopy Sciences takes special precautions to assure a polymer-free, pure glutaraldehyde. 4 to (-18)°C.

Electron Microscopy Sciences Glutaraldehyde Aqueous 8%, EM Grade 10 ML
OCHCH₂CH₂CH₂CHO F.W. 100.12
Aqueous glutaraldehyde, the universal fixative for electron microscopy, is purified to EM grade from commercial grade by "all-glass vacuum-distillation". It is the highest possible quality, free from polymers and other contaminents. Each lot is assayed prior to shipping assuring consistent purity and the highest possible quality.
If stored properly, our Glutaraldehyde has a very long shelf life. EM grade aqueous glutaraldehyde, stored in volumes greater than 100 ml, with repeated defrosting and recapping, will polymerize in time, producing an absorption peak of 235nm rather than the 280nm of pure EM grade. The presence of polymerized glutaraldehyde greatly reduces its efficiency as a cross-linking agent, preventing proper fixation. For this reason, we provide 10 ml ampoules sealed under dry nitrogen and 100 ml bottles that are kept refrigerated until it is shipped.
Grade: EM Grade
Electron Microscopy Sciences Aqueous Glutaraldehyde 25% in Serum, EM Grade 10 ML
Over the years, many of our valued customers have requested purchasing our aqueous Glutaraldehyde in serum vials. This packaging allows the user to puncture the special non-reactive seal with a hypodermic syringe and draw out the exact quantity of aqueous Glutaraldehyde needed without opening the container. This packaging assures freshness and purity of the aqueous Glutaraldehyde at all times.
Grade: EM Grade
