Orcein Stain Kit (For Hepatitis B and Elastic Fibers)
The Orcein Stain may be used in histology procedures for the visualization of Hepatitis B surface Antigen (HBsAg), elastic fibers, and copper associated proteins. HBsAg appears as irregular shaped aggregates in the cytoplasmic region of the cells. This reagent may be used on formalin-fixed, paraffin-embedded sections.
HBsAg: Dark Red/Brown
Elastic Fibers: Dark Red/Brown
Copper Assoc. Proteins: Dark Red/Brown
Background: Light Reddish/Purple
