Paraffin Tissue Section

Introduction to Paraffin Tissue Section

Formalin fixed, paraffin embedded (FFPE) whole tissue sections are an ideal way for rapidly determining the cellular localization of DNA, RNA and protein markers. This is a pertinent step for investigating and validating biological targets and their relevance in diagnostics or drug development.

BioChain’s Paraffin Tissue Sections have been meticulously selected and identified by our board licensed pathologist and are based on the sample repository network established by the IRB-approved ethical standard and procedures. Our FFPE tissues have been fixed in formalin after being excised, sectioned at 5 µm thickness, and mounted on positively charged glass slides. Our repository covers a wide variety of species and diseases including human (adult and fetal) normal tissues, human diseased and tumor tissues, as well as mouse, rat, and monkey tissues. We also offer custom sample preparation and specimen procurement to fit your needs.


  • Tissue from a wide variety of difficult to obtain tissue sources
  • Suitable for both immunohistochemistry and in situ hybridization assays
  • Multiple tissues or single tissue per slide
  • Documentation of tissues' clinical histories available
  • Applications

  • Cellular localization of tissue specific mRNA and protein expression
  • In situ hybridization, immunohistochemistry, and in situ PCR application
  • Comparison of the locations of novel genes in different tissues
  • FFPE DNA and RNA isolation
  • Antibody validation
  • Quality Control

  • At least one of the tissue slides from each lot was stained with H & E to ensure the quality
