The Benefits of Using Tissue Microarrays (TMAs) In Your Lab

Tissue microarrays (TMAs) are paraffin blocks that include multiple samples from different tissue types meant to provide a comprehensive multiplex staining profile. The sections from TMA blocks can be used for all types of tissue staining techniques, including immunohistochemistry and in situ hybridization. 

In order to create a TMA block, cylindrical tissue samples are collected from a set of individual donor tissue blocks and then embedded in an empty ‘recipient’ paraffin block in an array formation. This allows labs to optimize IHC and ISH procedures in a few ways.
