Fig 6

A. The tissue specimens of hepatocellular carcinoma, renal cell carcinoma, prostate adenocarcinoma, colon adenocarcinoma or lung adenocarcinoma were stained with purified novel mouse anti-human CD26 mAbs (U16-3 (i) or U38-8 (ii)). Original magnification, 40x. B, C, D. The EDTA-decalcified (left panels) or formic acid-decalcified (right panels) tissue specimens of normal human bone and bone marrow (B), formic acid-decalcified tissue specimens of metastatic thyroid carcinoma in the bone (C), or the tissue specimens of primary thyroid carcinoma without decalcification (D) were stained with purified goat anti-human CD26 pAb (R&D Systems (i)) or purified novel mouse anti-human CD26 mAbs (U16-3 (ii) or U38-8 (iii)). Original magnification, 10x (B, left panels of C, D) or 40x (right panels of C). All specimens were counterstained with hematoxylin.
