Cell Marque PAX-8 (SP348) Rabbit Monoclonal Antibody

PAX-8 is a transcription factor expressed during embryonic development of Müllerian organs, kidney, and thyroid, with continued expression in neoplastic transformation of some epithelial cell types of these mature tissues.¹

It can be useful for marking several types of carcinoma including, but not limited to, ovarian serous carcinoma, clear cell renal cell carcinoma and papillary thyroid carcinoma.^1-5 Certain anti-PAX-8 antibodies may react with lymphocytes and their neoplasms, which has been attributed to cross-reactivity with PAX-5 due to sequence homology between PAX-8 and PAX-5, but clone SP348 does not exhibit reactivity in these cell types.⁶
