Tanen

Phosphotungstic acid haematoxylin (PTAH) is a mix of haematoxylin with phosphotungstic acid, used in histology for staining. It stains some tissue in contrasting colors in a way similar to haematoxylin and eosin stain, as phosphotungstic acid binds to tissue proteins. It is used to show gliosis in the central nervous system, tumours of skeletal muscles, and fibrin deposits in lesions. Muscle is stained blue-black to dark brown, connective tissue is pale orange-pink to brownish red, fibrin and neuroglia stain deep blue, coarse elastic fibers show as purple, and bone and cartilage obtain yellowish to brownish red color. PTAH is ideal for demonstrating striated muscle fibers and mitochondria, often without a counterstain.

Ptah also refers to the asteroid 5011 Ptah In Egyptian mythology, Ptah (also spelt Peteh) was the deification of the primordial mound in the Ennead cosmogony, which was more literally referred to as Ta-tenen (also spelt Tathenen), meaning risen land, or as Tanen, meaning submerged land. It was said (in the Shabaka Stone) that it was Ptah who called the world into being, having dreamt creation in his heart, and speaking it, his name meaning opener, in the sense of opener of the mouth. Indeed the opening of the mouth ceremony, performed by priests at funerals to release souls from their corpses, was said to have been created by Ptah. Atum was said to have been created by Ptah to rule over the creation, sitting upon the primordial mound.
