Paraffin tissue slides suitable for use in identifying cellular localization of RNA or protein using in situ hybridization or immunohistochemistry. Human tissue of ~5um thickness is paraffin embedded and mounted on a positively-charged glass slide.||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 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 12 months after receipt.
