Immunohistochemical Staining
Immunostaining of frozen or paraffin-embedded tissue sections will be run on the Dako automated Link 48 immunostainer.
Whole Sliding Scanning
New policy-scanned images will be stored for 15 days from the day of project completed notification. After that time, all images will be deleted.
- No microscope needed
- Diagnostic quality, high-throughput resolution images up to 40X magnification, ideal for routine scans
