Si(CH3)4 M.W. 88.22
An organo-silicon compound tetramethylsilane (TMS) is used as an internal standard for nuclear magnetic resonance (NMR). It is chemically inert and has a boiling point of 26.6°C which is lower than acetone (53.6°C), and other highly volatile liquids, such as diethyl ether (34.5°C) and 1,2-epoxy propane (36.4°C). It is soluble in most organic solvents but insoluble in water. All of these properties make TMS an ideal solvent for tissue drying, which preserves excellent tissue surface details. Dey, Sudip. Et al. (1989). A new rapid method of air-drying for scanning electron microscopy using tetramethylsilane. J. of Microscopy, Vol 156, pp. 259-261.

Tris Buffer pH 10.0 (10x)
Description: This buffer is intended for heat-induced antigen retriever on formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In IHC most commonly used fixative like formalin mask tissue antigens (cellular, membrane and nuclear) by cross-linking process, this results in poor or no staining in IHC. The use of this buffer on FFPE tissue section improves accessibility of antibodies to tissue antigens.
Storage: 2-8°C. DO NOT FREEZE
Intended Use: 1x buffer solution is intended for heat-induced antigen retriever in IHC. Please refer to primary antibody protocol.
Reagent: 10x, pH 10 antigen retriever solution.
Preparation of Working Solution: Dilute this 10x buffer as needed (e.g. 90 ml of deionized or distilled water + 10 ml of this buffer), mix well, 1x buffer can be stored at 2-8°C.

Trypsin ReagentDescription: Trypsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In IHC most commonly used fixative like formalin; mask tissue antigens (cellular, membrane and nuclear) by cross-linking process, this results in poor or no staining in IHC. Trypsin digestion improves immunoreactivity of some antigens in FFPE tissue sections. For cytokeratin clone AE3 and AE1/AE3, this enzyme works much better than boiling the tissue with citrate buffer.
Storage: 2-8°C. DO NOT FREEZE
Intended Use: Use as antigen retriever for some antibodies in IHC. Please refer to primary antibody protocol for IHC.

Substitute for Uranyl Acetate
EMS is proud to introduce UranyLess, a new contrast stain solution for TEM, for all of your negative staining applications. It is an amazing substitute for Uranyl Acetate with similar results.
After only a minute of contact, UranyLess' fast-acting, non-radioactive lanthanide mix is finished staining your sections or deposits (see protocols below). If needed, lead citrate is recommended to increase the contrast. TIP: To prevent precipitates, use room temperature distilled water.
UranyLess's pH level is about 6.8-7. The 30 ml airless bottle will stain approximately 1500 grids. The airless bottle increases shelf life, eliminates CO2 contamination, and produces less waste - the solution pumps out in perfect amounts without leaking or spilling. UranyLess is also available in a larger amount for use in automated staining equipment. When using UranyLess for automated staining, do not wash longer than 10 minutes or you run the risk of losing all contrast.
UranyLess has been tested on many biological tissue (animal and plant): intestine, skeletal and cardiac muscle, liver, kidney, adrenal gland, nerve, cell culture, plant tissue, and also on negative staining of bacteriophage, bacteria, and polymers. UranyLess is ideal because of its ability to stain any kind of material and results are reproducible. To see the effectiveness of Uranyless, please visit the UranyLess Image Gallery.
Lead Citrate 3%
UranyLess has a strong contrasting power, however, we recommend a Lead Citrate counterstain to enhance the contrast. You can follow the protocol of the UranyLess / Lead Citrate double contrast by watching the video. EMS recommends Lead Citrate 3%, ready to use. The special pump delivers the product without letting in air, thus preserving the solution and preventing CO2 dissolution. It is convenient to use because it performs in any position, even upside down. Comes in either a 30 ml Airless bottle or a 30 ml Airless Syringe. The Syringe is meant to be used exclusively with the RMC TEM Stainer QG3100

It is intended to be used as a replacement for xylene where the hazards associated with aromatic hydrocarbon vapors are to be reduced. Museum-quality tissue slides can be prepared with Hitosol without change in protocol or procedure. Histosol is manufactured from petrochemical products and is miscible in all proportions with ethanol, isopropanol, and t-butanol. It is also miscible with all paraffin-based tissue embedding media and all permanent mounting materials.

Hemo-De® Xylene Substitute
An intensive study from 1992 throughout 2000 has shown that Hemo-De® (d-Limonene) a terpene-based chemical with a pleasant citrus fragrance, was able to replace many of the clinical laboratories toxic reagents, such as carbol-xylene, xylene, ethyl acetate and formalin.
In Parasitology – Hemo-De replaces ethyl acetate in the concentration procedure; Hemo-De replaces carbol-xylene, xylene and formalin in the trichrome procedure.
In Histology – Hemo-De replaces xylene in most all procedures. Hem-De is a superior solvent and Clearing agent that can be used in all tissue processing, deparaffiniating and slide preparation.
- Soluble with alcohol and mounting media
- Biodegradable, non-corrosive, non-flammable (Combustible)
- Contains no benzene and no toluene
- Low toxicity levels
- Minimal tissue shrinkage
- Reasonably fast drying and leaves no residue
In Research and Medical – Hematology, Cytology, Pathology, Microbiology, Histology, Pathology, Hospital
