Anti-DPP4 Antibody

Supplied through Antibodies.com, this primary antibody is a rabbit polyclonal reagent raised against dipeptidyl peptidase 4 (DPP4) and is intended for research use only. It is presented as a 50 µl liquid stock at approximately 1 mg/ml in phosphate buffered saline (PBS) containing 15 mM sodium azide at roughly pH 7.2, with an estimated purity of greater than 95%. The antibody is unconjugated and of the IgG isotype, making it suitable for standard detection workflows and convenient downstream labelling by the end user. Western blot (WB) is the validated application, with the reagent having been assessed on samples from human, mouse and rat origin, providing broad coverage across the most commonly used mammalian model systems. The host species is rabbit and the clonality is polyclonal, which supports recognition of multiple epitopes on the DPP4 target and can be advantageous when working with denatured lysate preparations typical of western blotting workflows. The protein target, DPP4, also known as CD26, is a 110 kDa type II transmembrane glycoprotein with dipeptidyl peptidase activity that is widely expressed on epithelial and immune cell surfaces and is a focus of interest in metabolism, immunology and oncology research. For handling, the product should be stored according to standard antibody storage guidelines (typically 2–8 °C for short term and –20 °C for longer term in aliquots), and the sodium azide in the formulation should be taken into account for any downstream applications that are azide-sensitive. Together, these characteristics make this Antibodies.com polyclonal anti-DPP4 antibody a practical choice for laboratories needing a robust, multi-species western blot reagent for the detection of endogenous DPP4.
