Would anyone please share any information regarding staining FFPE tissue with Alkaline Phosphatase for osteosarcomas. Is it solely performed by IHC or are there any special stains that could be used?TIA Rhonda McCormick BS, HT (ASCP)cm Histology Diagnostic Lab Supervisor College of Veterinary Medicine Texas A&M University Lab: 979.845.5149rmccormick10 at tamu.edu
