ELISA analysis with novel anti-CD26 mAbs. Non treated native soluble CD26 (sCD26) or urea treated denatured sCD26 was incubated with the hybridoma supernatant (clone 1, 5, 11, 16, 18 or 19) or purified mouse anti-CD26 mAb (5F8) or commercial mouse anti-CD26 mAb (MBL, clone 44–4) or purified goat anti-CD26 pAb (R&D Systems). The absorbance at 450 nm/570 nm was measured, and data are shown as mean ± S.E. from three independent experiments.
