Immunohistochemistry Services
The Histopathology Shared Resource provides Immuhistochemistry services which include:
- Testing and titering new antibodies, both monoclonal and polyclonal. The latter should be either a purified IgG fraction or affinity-purified. (Straight serum is not suitable for immunostaining).
- Optimization of staining to enhance detection and reduce background.
- Epitope retrieval techniques (pre-treatment with heat and/or proteases)
- Specialized secondary detection reagents
- Avidin/biotin blocking steps
- Double- and triple-antibody stains using multiple chromagens.
Manual and automated immunohistochemistry
Immunohistochemistry services provided by the Histopathology Shared Resource (HSR) can be performed using the automated Ventana Benchmark XT platform or by manually staining the slides by hand.
*Please note: HSR does not carry antibodies in stock for general use. Researchers must provide the antibody to the core for immunohistochemistry services requested. Once the request is completed, HSR will return the remaining antibody to the researcher along with the samples.
Contact the Histopathology Shared Resource for more information.
Previous optimized antibodies
The Histopathology Shared Resource (HSR) has performed various Immunohistochemistry stains (IHC) for researchers and can offer some insight based on previous staining experiences. It is required to discuss any IHC submissions with the Histopathology Shared Resource team to determine and review the details of this upcoming request.
Below is a list of antibody stains performed by the core for previous projects.
- For a list of previous antibodies optimized using the Ventana Benchmark XT Platform, refer to our Automated Immunohistochemistry Services*
*Please note that the Histopathology Shared Resource does not carry any antibodies in stock. The researcher is responsible for purchasing and providing any antibody or reagent needed for their project.
It is required to discuss an IHC request with the Histopathology Shared Resource team before any submissions.
Contact us to discuss optimization of a new antibody.
