Has anyone used the Serotec # MCA 1746G mouse anti-porcine CD31 or #MCA 1747 mouse anti-porcine CD31 on FFPE porcine arteries? If so, can you give recommendations for retrieval and dilutions? The website shows they have "Not determined" reactivity. Thanks in advance for any recommendations. Cindy Baranowski, HT(ASCP)
