Scope of Class

The objective of the course is to provide researchers with the opportunity to learn the theory and practice of immunogold labeling. Participants will process their own samples under the expert guidance of our tutors, who are experts in immunogold silver staining techniques.

During the workshop attendees will receive theory, including but not limited to immune detection, in situ hybridization, silver enhancement, as well as background issues. There will be time for practice, as well. Attendees will be able to work with their own specimens, as well as ones we will have prepared. A full review of incubation methods, testing of antigenicity and reactivity, complete principles of immunogold labeling, and preparation of conjugates for EM and LM will be covered.


The EMS Microscopy Academy
Located in Hatfield, Pennsylvania, the Academy provides electron microscopy classes, workshops and training sessions for all fields of microscopy, including materials science and biological science.


Lecture, demonstration and hands-on practice, as well as round table discussion. Participants may bring their own samples to work on during lab time.

Note: Specimens need to be "ready to use", e.g., sections of chemically fixed cells on coverslips. For each combination of primary antibody and gold conjugate that you want to test during the workshop, you need at least 3, preferably 4, specimens. This enables you to test different dilutions of the primary antibody and to check the immunogold/silver reagents (negative control).

For pre-embedment immuno labeling, also include specimens that will be immuno labeled for evaluation on the light microscope. These specimens are used to see if the experiment is successful. During the workshop there is no time/no option to further process pre-embedment specimens for EM evaluation. Plastic embedment and sectioning needs to be done at your own facility.

Peter van de Plas
Peter has a background in histology and immunocytochemistry and joined Aurion in 1991. During the pioneering phase of Aurion in the early nineties, he worked closely with Dr. Leunissen in founding a firm basis for Aurion. He contributed not only to the development of product applications, but also in designing the Aurion Immunogold Silver Staining workshop. He has been invited to many international microscopy conferences and workshops, and is especially experienced in providing hands-on training. Former workshop attendees and customers appreciate Peter for his technical support on and his thorough knowledge of the immunogold silver staining techniques. The Aurion Immunogold workshops in Europe, Asia, Australia, and the US have all been fully attended and very well received.

Michael Kostrna
Michael was the program director of the Electron Microscopy Technician program at Madison Area Technical College and has more than 35 years in EM technical education and research experience. He has been training EM students for 29 years and has developed curricula and lab exercises for TEM, SEM, OLM, lab safety, introductory and advanced biological EM, EM, maintenance, and x-Ray microanalysis. He has worked with companies such as SC Johnson Polymer, Dow Chemicals, Io Genetics, Virent Technologies, ABS Global, NanoOnocology, and Microscopy Innovations, and in the process gained insight to the various applications of EM.

Al Coritz
Al has been working in the Electron Microscopy field for 38 years, beginning at the Yale School of Medicine and ending up on the commercial side with several key EM companies. His specialty is Cryo-techniques and Thin Film Technology: i.e. Freeze Fracture/Rotary Shadowing, High Pressure Freezing, and more. He is currently with Electron Microscopy Sciences where he has been the Technical Director for over 20 years.
