The continuous liquid base in stains as well as chemicals and frequent washing throughout the immunohistochemical staining procedure, especially immediate rinsing after antigen retrieval heating, pose a significant risk for loss of tissue sections or cells. The surface of the CITOTEST® Color-PLUS™ slides is coated with a durable, specially developed adhesive layer that reliably binds the tissue sections to the glass, significantly reducing the possibility of tissue section or cell loss.
