Roche launches new chromogen for cancer research

DISCOVERY Yellow Kit to advance IHC and ISH multiplexing

Mar 11, 2016, 10:00 ET from Roche

TUCSON, Ariz., March 11, 2016 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the launch of the DISCOVERY Yellow Kit1, the newest addition to the comprehensive collection of VENTANA modular-based detection kits to aid in the identification and profiling of cancer biomarkers and tumor cell populations. DISCOVERY Yellow is an alkaline phosphatase-based detection chemistry for tissue diagnostics that produces a unique, transparent yellow signal that is not washed away during alcohol dehydration like some precipitating dyes, fitting seamlessly into routine laboratory workflow.

This unique detection kit fosters innovative research with the DISCOVERY ULTRA2, a fully automated immunohistochemistry (IHC) and in situ hybridization (ISH) staining platform. It can be used in combination with other dyes, expanding IHC and ISH multiplexing capability, by providing a distinct color that contrasts with other chromogens. The DISCOVERY Yellow color is complementary to other modular chromogens including DISCOVERY Purple, DISCOVERY Red and DISCOVERY Silver, giving users a variety of chromogens to choose from for multiplexing in which multiple markers can be simultaneously studied with limited tissue samples.

Highly significant to innovative research, DISCOVERY Yellow is designed to be used in conjunction with other chromogens for detecting signal co-localization, in which the spatial overlapping of two signals can be studied by forming a third color.

"By providing additional staining detection flexibility to the research community, we give our customers more options in their multiplexing applications, allowing for further advancement in their biomarker research," said Ann Costello, Head, Roche Tissue Diagnostics. "Our beta test customers are very impressed with the strong, distinct, crisp and transparent staining quality by DISCOVERY Yellow on different types of tissue."

DISCOVERY Yellow Kit is supplied in ready-to-use dispensers that can be fully automated on the DISCOVERY ULTRA system to empower researchers with increased flexibility and unprecedented productivity for increasingly complex assay requirements.
