Hematoxilina

Descripción:

Hematoxilina, con el número CAS 517-28-2, es un colorante natural derivado de la madera del árbol de palo de tinte (Haematoxylum campechianum). Se utiliza principalmente en histología y microscopía como agente de tinción, particularmente para tejidos biológicos. Hematoxilina exhibe un color azul profundo a púrpura cuando se oxida, lo que le permite unirse eficazmente a los ácidos nucleicos, lo que lo hace valioso para resaltar los núcleos celulares en muestras de tejido. El colorante se utiliza a menudo en conjunto con eosina, un contracolorante, en la técnica de tinción ampliamente empleada de Hematoxilina y Eosin (H&E). Hematoxilina es soluble en alcohol y agua, y sus propiedades de tinción pueden mejorarse mediante oxidación, generalmente lograda utilizando agentes como el iodato de sodio o el permanganato de potasio. Además de sus aplicaciones en la investigación biológica, Hematoxilina también se ha explorado para posibles usos en varios campos, incluidos productos farmacéuticos y cosméticos, debido a sus propiedades antioxidantes. Sin embargo, es esencial manejar Hematoxilina con cuidado, ya que puede ser tóxico en ciertas concentraciones.

Hematoxylin hydrate

CAS: 517-28-2

Hematoxylin hydrate is a histological stain, which is derived from the heartwood of the logwood tree, Haematoxylum campechianum. This compound undergoes oxidation to become hematein, which then forms a complex with metal ions, commonly aluminum, yielding a dye capable of binding to nucleic acids. The mode of action involves the selective binding to the negatively charged phosphate groups of nucleic acids, primarily in the cell nuclei, resulting in a blue to purple coloration.

Hematoxylin

CAS: 517-28-2

Hematoxylin is a histological stain, derived from the heartwood of the logwood tree (Haematoxylum campechianum), which is a tropical plant native to Central America. Its mode of action involves oxidizing hematoxylin to hematein, which then binds with tissue components in the presence of a mordant, typically aluminum salts. This results in a color change where cell nuclei appear blue or purple under a microscope.
