Tissue macroarray: a simple and cost-effective method for high-throughput studies.
The tissue microarray technique is a powerful technique that can examine many clinical specimens in a single slide. However, this technique requires a specialized instrument for the construction of tissue microarray block. The authors describe an alternative tissue macroarray technique for the simultaneous analysis of multiple clinical specimens on a single slide. As an example of this method, the authors assembled 12 tumor samples from 12 different paraffin blocks on a glass slide and then immunostained with hMLH1 antibody. This simple method does not need specialized equipment and should be an alternative efficient approach for large-scale clinical specimens.
