msdsAcrytol Mounting Mediaarrow12Acrytol Mounting Media

Acrytol is a rapid-drying mounting medium which enables slides to be screened immediately. It has a low viscosity, allowing the medium to flow easily. It also prevents air bubbles from becoming trapped.

Acrytol contains an antioxidant to inhibit stain fading and prevent the formulation of annual rings. A thin coating of Acrytol is all that is needed to adhere a coverglass to a microscope slide.

msdsAron Alpha® -Ethyl Ultra Speed Adhesive (Quickbond)arrow12Aron Alpha® -Ethyl Ultra Speed Adhesive (Quickbond)

Aron Alpha , type 200 is a one component, room temperature curing structural adhesive composed mainly of alpha cyanoacrylate monomer in a liquid state. When this monomer is applied in a single thin coating to the bonding surface of the material, it instantly solidifies through polymerization to produce an extra high strength, colorless bond with virtually no shrinkage. Aron Alpha bonds almost any nonporous material except fluorocarbons. Solvents such as gasoline, propane, oil, alcohol or benzene do not affect resinified Aron Alpha. The adhesive itself contains no solvents. The Aron Alpha bond has a high tensile strength but a relatively lower shear strength. Aron Alpha is not a gap filler. Good surface contact is essential. Meets MIL-A-46050 C. Ideal for the bonding of tissues to a tissue-slicer, tissue block or to a blank block etc.

msdsBiobond; Tissue Section Adhesivearrow12Biobond; Tissue Section Adhesive

Having prepared the tissue specimen for immunolabeling it is then imperative to perform the incubations with a protocol designed to maximize the specific signal and minimize the background. Some incubation conditions may cause the tissue sections to be removed from the glass slide. Typical tissue section adhesives such as poly-L-lysine, Elmer's glue, chrome alum, etc... are not suitable for use with immunogold labeling because of the increased background caused by the attraction of gold particles to the adhesive on the slide.

Furthermore, the surface of glass slides is uneven and it is activated by the silicon tetrahedral structure. It, therefore, provides active sites for absorbtion of proteins or reactions with chemicals and reagents. Thus, it is important to minimize this possibility by coating the surface with a material that is of low reactivity towards reagents. BIOBOND produces a very strong adhesion between the glass slide and the tissue section for subsequent incubations, as well as a protective layer to minimize the interaction between the charged glass surface with the reagents.

BIOBOND is suitable for all kinds of tissue specimens including but not limited to paraffin wax, resin sections, cell smears, cytospins and cryostat sections.

BIOBOND is supplied in a 20 ml vial, which is sufficient to coat at least 1000 slides.

msdsarrow12Biomount™

Some mounting media oxidize rapidly upon exposure to air, forming carboxyl groups. This can be more pronounced when sections have been cleared in a solution containing aldehyde. It is sometimes observed that the immunogold/silver signal fades after a few weeks, or even in a shorter time, from sections that have been mounted with these media under cover slips. The silver is still present, but has formed translucent silver carboxylate salts. Visibility can be retrieved by removing the cover slip and washing in xylene and then immersing the slide in photographic developer, but this is a tedious procedure.
BIOMOUNT is a specially formulated mounting medium that reduces fading of immunogold/silver signals in sections on glass slides. It is suitable for resins as well as wax embedded sections of tissue.

Application Notes:

Surface Preparation: All surfaces must be free of oil, dirt, corrosives, oxides, paint or other foreign matter.

Mixing: Two-component products should be mixed thoroughly to a uniform consistency. Preheat high viscosity epoxies to approximately 125°F to facilitate pouring and mixing.

Application: In most cases, the adhesive should be applied to both surfaces maintaining a glue line of less than 10 mils (25.4µm). After assembling the parts, pressure should be applied to the assembly to prevent warpage and reduce air entrapment. Refer to curing guidelines in above property chart.

Mounting Medium for all Laser Scanning and Conventional Microscopearrow12Mounting Medium for all Laser Scanning and Conventional Microscopes

A Revolutionary New Mounting Medium which helps to control the effects of Refraction.

THESE MOUNTANT SOLUTIONS:

  • Have a refractive index of 1.52 to match the refractive index of your slides and coverslips.
  • Are simple to use – Just apply the solution to the specimen followed by a cover slip.
  • The solution may be kept at room temperature – comes with dropper tip to aid in dispensing.
  • All mountants are water miscible (aqueous glycerol based), and therefore the specimen does not need to be dehydrated prior to the addition of the mounting solution.
  • Has a pH compatible with the specimens: CFM-1 has a pH of ~6.5, and CFM-2 has a pH of ~8.5.
  • Contains an antifadent to help reduce the bleaching of the fluorochromes (CFM-1 Plus Antifadent).
  • May be used as a immersion oils in addition to being a mountant solution and since they are water-based, they facilitate cleaning the microscope optics.
a CFM-1 and CFM-1 Plus Antifadent

This glycerol-phosphate buffered saline based mountant solution has been specially formulated so as to have a refractive index of ~1.52 @ room temperature. The addition of antifadent is to retard the bleaching of fluorochromes. Its refractive index is similar to glass; therefore effects of refraction on image quality are minimized. The CFM-1 plus antifadent will be particularly useful for high magnification work, where immersion oils are use to minimize distortion of the image due to the refraction of the viewing light and where bleaching of the flurochrome occurs.

The solutions should also be very valuable for laser scanning microscopy where, three-dimensional imaging of specimens is carried out e.g. with confocal fluorescence microscopy where integrity of the image has to be maintained.

Both solutions are medium viscosity, and water-clear.

CFM-1 Plus Antifadent have a pH of ~10.

CFM-1 has a pH of ~6.5.

aCFM-2 Mountant

This glycerol-tris-buffered based mountant solution has been specially formulated to have a refractive index of ~1.52 (at room temperature) i.e. a refractive index similar to glass so that the effects of refraction on image quality are minimized. This mountant solution may also be used as an immersion oil. The CFM solutions will be particularly useful for high magnification work where immersion oils are used to minimize distortion of the image due to refraction of the viewing light. The solutions should also be particularly valuable for lasing scanning microscopy where three-dimensional imaging of specimens is carried out e.g. with confocal microscopy.

The solution has a medium viscosity, and it is water-clear, and has a pH of ~8.5.

CITIFLUOR™ - Antifadent Mountant Solutions arrow12CITIFLUOR™ - Antifadent Mountant Solutions

A mounting medium for immunofluorescence, which overcomes the problems of fading.

This mounting media is designed to reduce the fading of the fluorescence of dyes used for labeling biological specimens.

In the technique of fluorescence microscopy, the fluorescence is stimulated by high intensity UV and/or visible light. Absorption of the light populates an excited state of the dye (usually a singlet state) and this leads to fluorescence. However, the excited state of the dye may undergo chemical reaction, which leads to destruction as evidenced by the fading of the fluorescence and consequent loss of the image. Citifluor™ mounting media is designed to solve this problem.

Selection of the appropriate product:

There is no universal antifadent due to the fact that biological material is so varied in nature that the fluorescence fading of fluorochromic conjugates is a complex process.

The general anti-fadents are AF1, AF2, and AF3. The AF87 is a specialist immersion oil-based antifadent.

AF1 (Glycerol-phosphate buffered solution containing an additive for use with labeled tissue sections). Should be used if you normally examine specimens in glycol solution. If you normally use saline solution with your specimens.

AF2 (Glycerol solution containing additives for use with labeled tissue sections) is simply a glycerol solution of the antifadent.

AF3 (Phosphate-buffered saline solution containing additives for examination of whole cell) is appropriate.

AF87, the antifadent, is contained in non-fluorescent immersion oil. It is designed for those requiring work at high magnification. It is useful for preventing the fading of such dyes as DAPI, which have the tendency to disperse in glycerol based mountant solutions.

CFPVOH is an aqueous solution of poly(vinyl alcohol) for use as a solid CFPVOH is an aqueous solution of poly (vinyl alcohol) for use as a solid mountant. Apply a few drops of the solution to your sample, and allow drying to give a clear film.

AF100 is a solution of antifadents to be used with CFPVOH when fading of fluorescence in the poly(vinyl alcohol) is a problem. To prepare a CFPVOH solution containing AF100, add 0.1ml of Af100 to 0.9ml of CFPVOH. If more or less of the solid mountant solution is required, mix
the reagent in the appropriate ratio. Once these solutions have been made up, they should be used within a period of days since the solution deteriorates on storage.

All of these products have a long shelf life, a minimum of 2 years. The solution can be stored at room temp-erature. With LD50’s >2000mg/kg (in rat), this product exhibits no toxicological problems.

arrow12M-Bond System

The M-Bond system includes M-Bond 43-B, M-bond 600 and M-Bond 610. These adhesives are high-performance epoxy resins, which are formulated especially for bonding strain gages and special-purpose sensors. When properly cured, these adhesives are useful in temperatures ranging from -452°F to +350°F (-269°C to+ 175°C) with M-Bond 43-B, and to +700°F (+370°C) for short periods with M-bond 600 and 610. In common with other organic materials, oxidation and sublimation effects at elevated temperatures limit life. M-Bond 43B is particularly recommended for transducer applications up to+250°F (+120°C) and M-Bond 610 for transducers up to +450°F (+230°C).

Shelf Life and Pot Life

At room temperature, M-Bond 600 has a useful storage life of approximately three months, while M-Bond 43-B and M-Bond 610 will last about nine months.

Once opened and mixed, M-Bond 600 and 610 have room temperature pot lives of two weeks and six weeks, respectively. Since M-Bond 43B is supplied already mixed, its pot life is about the same as its shelf life when kept in a tightly closed container. These periods of adhesive usefulness can often be doubled by refrigeration at +30° to +40°F (0 to +5°C). Never open a refrigerated bottle until it has reached room temperature.

Curing Time

M-Bond 43B is about 2 hours at +375°F (+190°C).
M-Bond 600 is about 3.5 hours at +350°F (170°C).
M-Bond 610 is about 3 hours at 375°F (190°C).
