Paraffin (FFPE) Tissue Arrays or Microarrays (TMAs) are a useful tool that can be used for the validation of biological targets and their potential clinical relevance in the development of diagnostics or therapeutics. BioChain’s...(Expand Details) paraffin tissue arrays allow for multiple histological analyses. They can also be used to study new protein markers, DNA or RNA molecules, and disease related genes. Therefore, our paraffin tissue arrays provide high throughput platforms for the rapid investigation of biomarkers associated with oncology, diagnosis, and disease therapeutics. We also provide customized array construction with tissues from other diseases and other species.
