This service offers comprehensive support for Tissue Microarray (TMA) technology, a high-throughput method for analyzing multiple tissue specimens simultaneously. The service includes TMA design, where researchers plan the arrangement and selection of tissue cores from donor paraffin blocks. Construction involves extracting small cylindrical tissue cores from various donor blocks and re-embedding them into a single recipient paraffin block in a precise grid-like formation. Once constructed, the TMA block can be sectioned, and the resulting slides contain hundreds of tissue samples, allowing for uniform staining and analysis across a large cohort. This platform is highly efficient for immunohistochemical staining, in situ hybridization, and other molecular techniques, enabling rapid target verification, expression profiling, and epidemiological studies.
