Matched Pair - Paraffin Tissue Sections

Introduction to Matched Pair - Paraffin Tissue Sections

BioChain is a leading manufacturer of Paraffin Tissue Sections, Arrays and Tissue Panels. Matched Pair Paraffin Tissue Sections have been generated from human tumors and the corresponding normal tissues of the same donor. BioChain offers Primary Pair (PP), as well as Primary and Metastatic Pair (PM) products. Primary Pair tissue specimens are those that have been sectioned from primary tumors and its adjacent unaffected normal tissue. Primary Metastatic Pair tissue specimens have been sectioned from primary tumors and corresponding metastatic tumors.

Each Tissue Section is produced using proprietary sample preparation technology from the finest quality of tissue specimens. The tissues are immediately put in liquid nitrogen after being excised and then meticulously selected for exceptional quality by our pathologist. Tissues are sectioned at 5 µm thickness and are carefully mounted on positively charged glass slides. Afterwards, the quality of each slide is verified by using H&E staining. This product is a useful tool for accelerating gene expression analysis by identifying tumor-specific genes and tumor metastatic genes. Patient demographic and disease related history is available for human tissue specimens.
