November 17: Seminar Series #3

More than a pretty picture: Advances in Quantitative Digital Pathology

Presenter: Charles W. Frevert, DVM, ScD, University of Washington at South Lake Union

Description: Advances in the research pathology laboratory have increased our ability to efficiently generate high-quality digital images on the expression and accumulation of mRNA, proteins, carbohydrates, signaling pathways, cells, and structures in healthy and diseased tissues. Quantitative digital pathology allows us to analyze these digital images to obtain objective, quantitative, and reproducible data suitable for statistical analysis. This webinar aims to provide an overview of the critical information required to analyze tissues stained using histochemistry, immunohistochemistry, or in situ hybridization.


October 27: Seminar Series #2The Importance of Preanalytics when Performing Immunohistochemistry

 Presenter: Stephen Hewitt, M.D., Ph.D., Center for Cancer Research, National Cancer Institute, Editor-in-Chief of The Journal of Histochemistry and Cytochemistry

Description: The quality of any assay is dependent on the quality of the specimen and reagents used to perform the assay. The Pre-analytic variable of cellular and tissue specimens have been historically under-appreciated. The competition of histomorphology versus biomolecular integrity result in complex decisions for the researcher. Dr. Hewitt will discuss the basic principles of pre-analytic quality, approaches to determining if a specimen is fit for purpose and common pitfalls based on inadequate specimen preservation.


October 13: Seminar Series #1 - Fundamentals of Microscopy: The Need for Contrast

Presenter: Paul Goodwin, Ph.D., Past-President, The Histochemical Society and Science Director, Cytiva

Description: The light microscope is one of the most ubiquitous instruments in a research laboratory yet most user lack a basic understanding of the instrument. In this lecture, Paul Goodwin will cover the basics requirements for microscopy (magnification, resolution, and contrast) and how those requirements are addressed with a special emphasis on contrast. The lecture will finish with a description of histochemistry and immunohistochemistry as ways of generating contrast with molecular specificity.
