• Performs immunohistochemistry to determine the quantity of  extracellular matrix deposits accumulated within secondary lymphoid tissues. 
• Generates high-resolution digital images of each immunohistochemistry stained sample. 
• Provides relevant data electronically, including a report with interpretations and conclusions. 

The process: 

• Collagen I, Collagen III, or Fibronectin immunohistochemistry is performed to ascertain the extent of extracellular matrix deposition (i.e., fibrosis) accumulated within secondary lymphoid tissues. 
  • To ensure consistency among assay batches, we utilize an automated immunohistochemistry system. 
• High-resolution digital images of each IHC stained sample are generated using the Aperio ScanScope CS System. 
• Regions of interest of a defined size are highlighted on each digital image using the Aperio ImageScope software regions tool. 
• High-resolution images of regions of interest are generated using a custom software program created by the Imaging and Visualization Group that automatically extracts regions of interest from the digital slide annotation layer. 
• Under the guidance of a subject matter expert, the core provides comprehensive quantitative image analysis using a custom series of unique actions in Photoshop with Fovea tools to determine the percent area in each high-resolution image that is occupied by fibrotic collagen. 

Includes sufficient basic consultation with a subject matter expert.
