Tissue was fixed in formalin immediately after excision, and embedded in paraffin. All paraffin embedded tissue products, including tissue array, tissue sections, and tissue panels can be used for both immunohistochemistry and in situ hybridization. These products are ideal for rapid cellular localization of RNA and protein expression. At least one of the tissue slides from each lot was stained with H & E to ensure the quality.||Every single tissue array is well maintained with good quality, but there might be some variations between slides, for example, one spot is missing cells due to the end of serial cut. But there should be no more than 3 spots are without expected cells.||Paraffin tissue slides can be used for both immunohistochemistry and in situ hybridization. They are ideal for rapid cellular localization of RNA and protein expression. ||Related Products:|Human Tumor Paraffin Tissue Slide Matched Pair (PP/PM):|Human paraffin tissue section matched pair products include: Primary Pair (PP), Primary and metastatic Pair (PM). PP consists of paraffin tissue sections of primary tumor and its adjacent normal tissue; PM consists of paraffin tissue sections of primary tumor and corresponding metastatic tumor. Paraffin tissue sections in each pair are prepared from the same donor. This product line is ideal for localization of tumor-specific genes and tumor metastatic genes. Tissue sections are 5um in thickness, and mounted on positively charged glass slide.||Paraffin Tissue Panel:|The panel contains 5 to 8 different tissues on one slide. Tissue panels are 5um in thickness, and mounted on positively charged glass slides.||Paraffin Tissue Array • FDA Standard Tissue Array:|Tissue arrays are 6um in thickness, and mounted on positively charged glass slides. Each tissue sample is about 1.5mm in diameter. A reference chart shows all the tissue names and their respective position on the array.||Storage and Stability:|Store at RT. Stable for 6 months after receipt.
