Anti-PGLYRP2 / Peptidoglycan recognition protein 2

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. PGLYRP2 antibody detects N-acetylmuramoyl-L-alanine amidase (also known as Peptidoglycan recognition protein 2), a secreted pattern-recognition enzyme involved in innate immunity. Encoded by the PGLYRP2 gene on chromosome 19q13.12, this protein belongs to the peptidoglycan recognition protein (PGRP) family, which binds and hydrolyzes bacterial peptidoglycan to modulate immune responses. PGLYRP2 contains a conserved amidase domain that cleaves the lactylamide bond between N-acetylmuramic acid and L-alanine in bacterial cell walls, leading to peptidoglycan degradation and reduced inflammatory potential. It acts as a first-line defense mechanism in epithelial barriers such as the liver and intestinal mucosa.PGLYRP2 is secreted primarily by the liver into the bloodstream, where it functions as a circulating peptidoglycan hydrolase. It neutralizes proinflammatory bacterial components, preventing systemic immune activation. In the gut, PGLYRP2 maintains microbiota balance by degrading bacterial fragments that would otherwise trigger toll-like receptor signaling. Genetic studies have associated PGLYRP2 variants with inflammatory bowel disease and asthma, highlighting its role in mucosal immune tolerance. The protein's enzymatic activity also protects against bacterial sepsis by reducing peptidoglycan-induced cytokine production.The PGLYRP2 antibody is widely used in immunology, microbiology, and liver biology research to study antimicrobial defense and immune modulation. Western blot analysis typically identifies a 62 kilodalton band corresponding to full-length PGLYRP2, while immunohistochemistry reveals cytoplasmic and secretory vesicle localization in hepatocytes and epithelial cells. This antibody supports characterization of innate immune pathways and microbiota interactions. Dysregulation of PGLYRP2 expression can lead to excessive inflammation or increased bacterial susceptibility.Mechanistically, PGLYRP2 differs from other PGRPs by possessing amidase enzymatic activity rather than bactericidal or signaling roles. It cooperates with PGLYRP1, PGLYRP3, and PGLYRP4 in forming an integrated host defense network. NSJ Bioreagents provides the PGLYRP2 antibody validated for its applications, ensuring reliable detection in studies of innate immunity, microbial recognition, and liver defense mechanisms.
