Problem addressed

Immunohistochemistry is a frequently used method in diagnostic pathology to specify the cancer (eg. T-cell lymphoma vs. B-cell lymphoma). Having a specific diagnosis, rather than just a general diagnosis such as lymphoma, is essential in modern medicine as different cancer types are best treated with different approaches. Further, some cancers are difficult to detect without immunohistochemistry.

  • AI technology enables a computer to virtually perform immunohistochemistry, replacing slow, expensive, and difficult-to-use antibody stains.
  • The neural networks behind AIstain are trained with accurate immunohistochemistry data obtained using antibodies, resulting in accurate outputs.
  • AIstain is implemented on the cloud, meaning pathologists anywhere in the world can use the technology by simply having a digital microscope and an internet connected computer.
