Tissue microarray are an important branch of biochip technology. Tissue microarray are miniature tissue arrays formed by grouping tens to thousands of small tissue sections on a single slide and are used to study the expression of the same gene or protein molecule in different cells or tissues.

CD Genomics offers a tissue microarray technology that uses mechanised preparation to integrate tens to thousands of donor paraffin tissue or cell specimens into blank recipient wax blocks to form tissue microarray wax blocks, which are transferred to silica and gelatinised slides via a sectioning aid system to create a high-throughput, large-sample tissue microarray biochip whose array size, arrangement and combination can be The size, arrangement and combination of the arrays can be pre-set to allow a variety of parallel histological or molecular biology analyses to be performed on a large number of different types of tissue samples of the same type or related to each other. We can offer our customers a wide choice of microarray formats, and we can accommodate a wide range of customised biological materials and customised plant and animal tissue microarray. Based on our tissue microarray technology, we can greatly help researchers to elucidate the similarities and variations of specific nucleic acid or protein molecules in tissue specimens and the expression of the same gene or protein molecule in different cells or tissues.

Technical features

• Small size, high throughput, standardisation, high information content, high energy and low consumption, large number of results in a single experiment.
• The conditions of the tissue samples on the chip are identical and there is excellent quality control.
• The wax block can be used for 100 to 200 consecutive sections, improving sample utilisation.

Tissue microarray can be applied to the following studies

• Biomarker identification and analysis
• Target expression in biological tissues
• Genomics for diagnosis
• Gene expression in biopathological samples
• Localisation analysis and detection of DNA, RNA and proteins in tissues

The application of tissue microarray technology has greatly facilitated the development of life science related research fields. In addition, tissue microarray technology can be applied in combination with many other conventional techniques such as immunohistochemistry (IHC) staining, in situ hybridisation (ISH), fluorescence in situ hybridisation (FISH) and other methods, and its application areas are expanding.
