| General Instructions |
Optimal Cutting Temperature Compound (OCT), commonly known as OCT compound, is a water - soluble mixture of polyethylene glycol and polyvinyl alcohol. Here is a detailed introduction:
Polyvinyl Alcohol: It accounts for 10.24% in the compound. It helps to increase the viscosity of the embedding medium, enabling it to firmly fix tissue samples and provide certain support.
Polyethylene Glycol: It makes up 4.26% of the compound. It can improve the fluidity of the embedding medium, facilitating better infiltration into the tissue and ensuring uniform embedding.
Non - reactive Ingredients: The remaining 85.5% are non - reactive ingredients. These ingredients play a role in stabilizing the formulation, regulating the freezing point and melting point, and improving the overall performance of the OCT compound. |
| Product Description |
Excellent Support: It can quickly solidify at low temperatures to form a stable supporting matrix, which provides uniform support for tissue samples and effectively protects the tissue structure, preventing tissue deformation and displacement during sectioning.
Good Water - solubility: It is soluble in water during the slide - floating process, leaving no residue on the slides, which will not increase the background staining in subsequent staining procedures and will not interfere with the microscopic observation and staining results of tissue samples.
Ant - icing Properties: It can reduce the formation of ice crystals in tissue samples, minimize the damage of ice crystals to cells and tissues, and help to maintain the original structure and biological activity of the tissue, which is especially suitable for the processing of soft and fragile tissues.
Wide Compatibility: It has good compatibility with various tissue staining processes, such as H&E staining, immunohistochemistry, and immunofluorescence, and is suitable for use in different histological experiments. |
