O.C.T.Compound

High-Performance Embedding Medium for Histology, Pathology & Research Laboratories

O.C.T. Compound (Optimal Cutting Temperature Compound) is a water-soluble embedding medium specially formulated for frozen tissue sectioning. It surrounds and stabilizes biological specimens during rapid freezing, allowing tissues to be sectioned smoothly in a cryostat without distortion, tearing, or compression.

Unlike paraffin embedding, frozen tissue embedding preserves enzyme activity, antigenicity, RNA, DNA, and protein structures because no dehydration, clearing, or high-temperature processing is required. This makes O.C.T. Compound indispensable for intraoperative frozen diagnosis, immunofluorescence, molecular biology, cancer research, neuroscience, stem cell research, and pharmaceutical development.

Chuangxin Medlab manufactures premium O.C.T. Compound using a carefully optimized water-soluble polymer formulation. Our compound offers excellent viscosity, rapid freezing performance, superior specimen adhesion, minimal background staining, and outstanding cryostat cutting performance.

Designed for hospitals, pathology laboratories, universities, biotechnology companies, pharmaceutical manufacturers, and research institutes, our O.C.T. Compound is compatible with most cryostat systems and frozen section workflows worldwide.

As a professional O.C.T. Compound manufacturer, Chuangxin Medlab supplies laboratory distributors and medical partners across more than 80 countries while providing comprehensive OEM and private-label manufacturing services.

Product Specifications

How O.C.T. Compound Works

O.C.T. Compound fills the spaces surrounding a tissue specimen and forms a stable support matrix during rapid freezing. This support minimizes deformation and allows thin, uniform sections to be cut in a cryostat.

Unlike paraffin processing, frozen embedding requires only minutes from specimen collection to section preparation, making it the preferred method for urgent pathological assessment and applications requiring preservation of biological activity.

Outstanding Cryostat Sectioning Performance

Our optimized formulation is engineered for smooth and reliable cutting across a wide range of tissue types.

Advantages include:

• Smooth ribbon formation

• Reduced tissue compression

• Minimal cracking

• Excellent edge definition

• Stable section transfer

• Consistent cutting performance

• Reduced specimen loss

These characteristics improve laboratory efficiency while enhancing section quality.

Excellent Tissue Morphology Preservation

Preserving tissue architecture is essential for accurate diagnosis and meaningful research results.

Chuangxin Medlab O.C.T. Compound helps maintain:

• Cellular structure

• Tissue morphology

• Nuclear detail

• Membrane integrity

• Protein localization

• Antigen preservation

• Enzyme activity

• Nucleic acid integrity

This makes it suitable for both clinical pathology and advanced biomedical research.

Optimized for Immunofluorescence and Molecular Biology

Many downstream analytical techniques require native biological structures to remain intact. O.C.T. Compound supports these requirements by eliminating exposure to high temperatures and organic solvents during embedding.

Typical applications include:

• Immunofluorescence (IF)

• Immunohistochemistry on frozen sections

• Enzyme histochemistry

• RNA extraction

• DNA analysis
