The most popular and consistent embedding medium for cryotomy

Tissue-Tek^® O.C.T. Compound is used to quickly embed fresh tissue specimens for frozen sections using a cryostat. Tissue-Tek O.C.T. Compound is a formulation of clear, water-soluble glycols and resins, providing a solid matrix to encapsulate tissue specimens and bond to the Specimen Holder for consistent sectioning in a cryostat working temperature of -10°C and below.
 
Undesirable background staining is eliminated as no residue is left on the slides during staining.
 
O.C.T stands for optimal cutting temperature. The high viscosity of Tissue-Tek O.C.T Compound results in fast freezing for optimal section quality.
 
The OCT Compound is sold in 4 oz (118 mL) squeeze bottles; 12/case.
