IHCWorld website

Here's another nice online resource: IHCWorld, the "Online Center for Immunohistochemistry". The introduction is a nice overview of IHC analysis. There's also a nice index to various resources for IHC image analysis, and a nice survey of Tissue Microarrays (TMAs).

What I find so interesting about IHC analysis is that the preparation of IHC samples is amazingly well-documented and very quantitative, but the analysis of the samples is less documented and subjective. Over time, improvements in techniques for imaging IHC slide samples and in the software to quantitatively analyze virtual slides will change this. The diagnosis will always be made by the Pathologist, but it will be made based on more quantitative information.
