Oolong Tea Extract (OTE) is a non-toxic and non-radioactive stain for electron microscopy. It is effective for fibrous connective tissues. OTE acts as a Tannin which allows complete post-stain lead citrate mordanting and gives satisfactory results. Powder is ideal for longer storage.

Osmiophilic reagent. With the Thiocarbohydrazide it´s possible to enhance the contrast of all osmophilic components of the cell, especially lipids, which hold the most osmium.

An indefinite shelf life due to a special purification process.

H₂NNHCSNHNH₂ / m.p. 171°C (decomposed)

(3,3',4,4'-Biphenyltetramin). Used as an ultrastructural protein tracer for immuno-cytochemistry. A possible carcinogen.

C₁₂H₁₄N₄ / m.p. 173°C

Glutaraldehyde tis he universal fixative for electron microscopy. Each lot is tested and assayed in a lab before we ship and guarantee its purity. Sealed under dry nitrogen. Refrigerated prior to shipment.
Serum vials allow puncturing the seal with a hypodermic syringe to draw out the preferred amount of glutaraldehyde without opening the vial to assure stability and purity.
