Western blot analyses showing detection of monomeric (approximately 105 kDa) and dimeric dipeptidyl peptidase-4 (DPP-4) forms (approximately 210 kDa) by detection (A) and capture (B) antibodies, respectively, used in the ARCHITECT DPP-4 Immunoassay. Lane 1: Dual Xtra Molecular Weight Markers; Lane 2: Empty; Lane 3: DPP-4 fragment (reduced and boiled); Lane 4: DPP-4 fragment (reduced and non-boiled); Lane 5: DPP-4 fragment (non-reduced and boiled); Lane 6: DPP-4 fragment (non-reduced and non-boiled). Abbreviation: DPP-4: dipeptidyl peptidase-4.
