BioChain's tissue products are based on the sample repository network established following the IRB-approved ethical standard and procedures. The 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. The tissues are immediately put in liquid nitrogen after being excised, and then identified by a board-licensed pathologist. Patient demographic and disease related history data are available.
BioChain's frozen tissue section line encompasses a large selection of tissue sections which are good for immunohistochemistry and in situ hybridization. The tissue sections are approximately 5-10 µm thick.
BioChain provides frozen tissue sections for a variety of experimental animals. A single animal normal fresh tissue with 5-10 µm is mounted on each positively charged glass slide. The slide is then fixed with cold acetone for consistent results with in situ hybridization and immunohistochemistry. These tissue sections are designed for rapidly identifying cellular localization of genes or proteins in monkey tissues.
