CAS 517-28-2

Ematossilina

Descrizione:

Ematossilina, con il numero CAS 517-28-2, è un colorante naturale derivato dal legno dell'albero del legno di campeggio (Haematoxylum campechianum). Viene utilizzato principalmente in istologia e microscopia come agente colorante, in particolare per i tessuti biologici. Ematossilina presenta un colore blu profondo a viola quando ossidato, il che consente di legarsi efficacemente agli acidi nucleici, rendendolo prezioso per evidenziare i nuclei cellulari nei campioni di tessuto. Il colorante è spesso utilizzato insieme all'eosina, un controcolorante, nella tecnica di colorazione ampiamente utilizzata di Ematossilina e Eosin (H&E). Ematossilina è solubile in alcol e acqua, e le sue proprietà di colorazione possono essere migliorate attraverso l'ossidazione, generalmente ottenuta utilizzando agenti come iodato di sodio o permanganato di potassio. Oltre alle sue applicazioni nella ricerca biologica, Ematossilina è stato esplorato anche per potenziali usi in vari campi, tra cui farmaceutici e cosmetici, grazie alle sue proprietà antiossidanti. Tuttavia, è essenziale maneggiare Ematossilina con cura, poiché può essere tossico a certe concentrazioni.

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.
