Tissue Microarray? The Tissue Microarray is a slide which contains numerous small tissue sections of various types. The diameter of each spot section can range from 0.6 to 2.0 mm and the sections can number from tens to several hundreds. Each tissue section is extracted from various donor blocks and transferred into a ready-made recipient block. The donor blocks are generally conventional formalin-fixed paraffin-embedded blocks but can also be different types, such as non-formalin-fixed, frozen, etc. What are the benefits? → Provides every feature of whole-tissue sections      For example, allows for observation of Proteins, RNA and DNA      from almost the same region. → Saves you     ＊ Time: a few days to even weeks or months     ＊ Money: a few hundred to ten thousands of dollars     ＊ Labor: one experiment or several hundreds → Minimizes experimental errors caused by differing conditions Who Needs TMA? → Those hoping to     ＊ Discover various molecular events or molecules     ＊ Find candidates for novel molecular targets, such as a         cancer gene     ＊ Validate candidates for novel molecular targets          using human tissue having a lot of necessary information. Why is the PETAGEN array the best ? → Thorough quality control → Almost no loss of tissue spots → Maximum preservation of tissue antigenicity → Allows for detailed pathological and clinical information → Largest variety of organs that can fit on a single slide → More..
