NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: Do not allow slides to dry at any time during this procedure.
For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; follow with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min.

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
DPP4 (D6D8K) Rabbit mAb recognizes endogenous levels of total DPP4 protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu491 of human DPP4 protein.
DPP4 (CD26) is a type II transmembrane glycoprotein expressed ubiquitously in most tissues and different cell types (1,2). The protein has a short cytoplasmic domain, transmembrane domain, a flexible stalk fragment and extracellular fragment (2). Both the catalytic peptide hydrolase domain and the beta-propeller ligand binding domain are located in the extracellular fragment (2). DPP4 is a multifunctional protein that exists in both a membrane bound form as well as an extracellular soluble form. As a peptidase, it removes N-terminal dipeptides sequentially from proteins with a proline or alanine as the penultimate P1 amino acid (3.4). DPP4 has been shown to cleave a wide range of substrates including GLP-1, BNP, substance P, etc. It is also involved in the regulation of related biological functions (5). In addition to it peptidase activity, DPP4 interacts with multiple important cell surface ligands, such as adenosine deaminase, fibronectin, and IGF2 receptor to influence processes like T cell activation, cell migration and proliferation (5). Several DPP4 inhibitors have been developed and their effects have been tested in the field of diabetes, cardiovascular disease and tumor immunity (2,5,6).
