Staining products CellPath

CellPath’s range of XMark dyes are used to permanently mark surgical tissue margins in histological specimens.

Marking dyes are available in 9 colours, with a standardised viscosity over the range. This ensures less variation in viscosity from one colour to another as compared to competitor products. It also allows the easy marking of both small and large specimens, without any dripping and running ensuring an even coverage, with any chosen colour.

• Consistent and high-quality product.
• Chemical and heat resistant to formalin, alcohols, xylene and wax for clear visibility both prior and after tissue processing.
• Dries in 3 minutes, improving laboratory workflow.
• Available in 60 ml or 250 ml bottles, induction sealed with a flip top lid.
• All 9 dye colours are easy to distinguish.
• Acrylic colour on the bottle label matches with the colour observed under the microscope, eliminating user errors.
• No special requirements during use as it is non-hazardous.
• Minimal penetration of the tissue surface.
• Strong adhesion qualities: marking dye will not interfere with diagnostic interpretations, ideal for radical prostatectomies.
• Non-flammable.

XMark Fix is a fixative spray usually applied after the application of XMark dyes, although it can also be applied to tissue prior to marking with dyes.

• Modifies the surface of challenging specimens.
• Aids the adhesion of XMark tissue marking dyes.
• Suitable and strongly recommended for fatty specimens.
• Clear.

XMark Ink Shield is a quick drying fixative spray, applied after a specimen is marked with a dye. It forms a protective layer on the marked surface whilst still allowing the tissue processing reagents to penetrate the tissue.

• Can be used with all dye colours and on all specimen types.
• Specially designed for use with the XMark range and ensures that specimen margins, marked with Xmark dyes (including yellow, orange and red), are durable and unaffected during tissue processing.
• Reduced leaching of dyes helps reduce the clogging up of the processors, eliminating potential failure and downtime.
• Enables strong adhesion of dyes on particularly fatty tissues.
• Clear.
