Peptide YY (PYY), a secretory peptide, is expressed by L cells (enteroendocrine cells) in the small and large intestine, Islet of Langerhans cells, testis, and in some central and peripheral neurons. Because PYY is released from L cells after feeding, it is thought to produce a satiety signal. While the regulation of appetite by PYY and GLP-1 have been studied extensively, recent evidence supports a role for PYY in Islet of Langerhans beta cell survival. PYY secretion is also modulated by gut microbiota, and levels of colonic PYY have reduced in rats with DSS-induced colitis, and in humans with inflammatory bowel disease (IBD), while circulating PYY increased in IBD.

Scientific Data Images for Human Peptide YY Antibody (2581A)
Detection of Human Peptide YY by Simple WesternTM.
Simple Western lane view shows lysates of human colon tissue and human small intestine tissue, loaded at 0.2 mg/mL. A specific band was detected for Peptide YY at approximately 3 kDa (as indicated) using 20 µg/mL of Rabbit Anti-Human Peptide YY Monoclonal Antibody (Catalog # MAB94563). This experiment was conducted under reducing conditions and using the 2-40. kDa separation system.Applications for Human Peptide YY Antibody (2581A)
