Scientific Data Images for Human Chymase/CMA1 Antibody
Detection of Human Chymase/CMA1 by Western Blot.
Western blot shows lysates of human small intestine tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Chymase/CMA1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4099) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Chymase/CMA1 at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human Chymase/CMA1 Antibody

Background: Chymase/CMA1
Chymases are a group of chymotrypsin-like serine proteases secreted by mast cells (1). They are synthesized as inactive precursors containing a 2-residue propeptide, which needs to be removed by dipeptidyl peptidase I/cathepsin C for the enzymatic activity (2). Human Chymase encoded by the CMA1 gene is known to be involved in hypertention and heart failure through its ability to convert angiotensin I (Ang I) to angiotensin II (Ang II), which plays a key role in the regulation of arterial pressure (3). In addition, it is also important in physiological and pathological conditions including inflammation, fibrosis and processing of cytokines (4). Therefore, designing a specific inhibitor for Chymase activity has been a pharmacologic strategy to develop therapeutic agents.
