Tissue Marking Dyes are intended as an aid in the orientation, of excised surgical specimens through frozen sectioning, processing, and sectioning, and subsequent microscopic examination of tissues. The marking of multiple margins with these dyes is especially useful for identification in skin biopsies, a technique known as Moh’s surgery. These dyes are normally applied to fresh tissue but may also be used with fixed tissue. Whether fresh or fixed, the tissue should be blotted to remove excess fluid from the surface before applying the dye. Tissue Marking Dyes will permanently bond to the tissue 1 to 2 minutes after application. The tissue can then be frozen and prepared for sectioning or placed in formalin or other fixatives and processed for paraffin embedding.
