Immunohistochemistry Services

Based on the principle of specific binding between antigen and antibody, the antigen (polypeptide and protein) in tissue cells can be determined by chemical reaction with the chromogenic agent (fluorescein, enzyme, metal ion and isotope) of labeled antibody, its localization, qualitative and relative quantitative research is called immunohistochemistry or immunocytochemistry.

Classification

  • According to the types of labeling substances, such as fluorescent dyes, radioisotopes, enzymes, ferritin, colloidal gold, it can be divided into immunofluorescence, radioimmunoassay, immunoenzyme labeling method and immunogold and silver method.
  • According to the dyeing steps, it can be divided into direct method (also called one-step method) and indirect method (two-step, three-step or multi-step method). Compared with the direct method, the sensitivity of the indirect method is much improved.
  • According to the binding mode, it can be divided into antigen antibody binding (such as peroxidase anti peroxidase method), affinity linking (such as ovalbumin biotin peroxidase complex method, Streptomyces avidin peroxidase method), polymer linking.

Features

  • Strong specificity

The basic principle of immunology determines that the binding between antigen and antibody is highly specific, and cross-reaction occurs only when there are cross-antigens in tissue cells.

  • High sensitivity

Antibodies that are diluted thousands of times, tens of thousands of times, or even hundreds of millions of times can still bind to antigens in tissue cells, making immunohistochemistry methods more and more convenient for routine pathological diagnosis.

  • Accurate positioning, combination of form and function

This technology can accurately locate antigens in tissues and cells through antigen-antibody reaction and color reaction, so that different antigens can be positioned and observed in the same tissue or cell at the same time.

We can provide you with fast, accurate and convenient services. Our pathology laboratory uses the latest technology, methods and equipment to meet all your needs. Please contact us for more details.
