The Clinical Biomarker Center (CBC) is an Arkana core research facility located in the same building as Arkana’s clinical lab, in close proximity to both renal pathology and neuropathology expertise.

The CBC serves multiple research projects at Arkana, both NIH-funded projects and industry-sponsored projects, as well as internal R&D. We also offer contract research services for biomarker discover and analysis to include multiplex imaging and image processing.

We are certified partners with Quanterix (formerly Akoya Biosciences) in their CRO Partnership Program and Vizgen (formerly Ultivue), specializing in multiplex imaging of human tissues. We have a Leica BondRx for automated staining protocols, a Quanterix PhenoImagerHT fluorescence and brightfield whole slide scanning microscope with InForm software for spectral unmixing, Halo AI image processing software, Halo Link access for remote collaborations, and specialized modules for niche image processing projects. The CBC also has access to an Olympus VS200 high-throughput fluorescence and brightfield scanning microscope, and a Leica laser scanning confocal microscope located on the same corridor, for both high-volume and high-resolution advanced microscopy.

Multiplexed immunofluorescent staining panels are developed for human tissues using Opal TSA technology and the Leica Bond RX autostainer.  Whole slide digital images of these tissues are generated using our Quanterix PhenoImager HT, with spectral unmixing using InForm software.  Digital images are processed using Halo AI software from Indica Labs, training algorithms for tissue classification and nuclear segmentation.  Cellular phenotypes are mapped based on biomarker expression using Halo’s HighPlex FL module. The final output from image analysis is the quantitative data map of every cell in the image, allowing for spatial statistical analysis in R.
