The CELA3B (N-term) antibody is designed to target the N-terminal region of chymotrypsin-like elastase family member 3B (CELA3B), a serine protease primarily expressed in the pancreas. CELA3B, also known as elastase 3B, is a member of the chymotrypsin family of digestive enzymes that play a role in hydrolyzing dietary proteins in the small intestine. It is secreted as an inactive proenzyme (zymogen) by pancreatic acinar cells and later activated by proteolytic cleavage in the duodenum. The N-terminal-specific antibody allows researchers to distinguish between the inactive proform and active forms of CELA3B, aiding in studies of enzyme maturation and regulation.
This antibody is widely used in Western blotting, immunohistochemistry, and immunofluorescence to investigate CELA3B expression patterns in pancreatic tissues, developmental biology, and pathologies such as pancreatitis or pancreatic cancer. Its specificity for the N-terminal region minimizes cross-reactivity with other elastase isoforms, including CELA3A, a closely related paralog. Research involving CELA3B also explores its potential as a biomarker for pancreatic disorders or its role in modulating inflammatory responses. By targeting the N-terminus, the antibody provides a reliable tool for elucidating CELA3B's functional dynamics in both physiological and disease contexts.
