PXN Antibodies

PXN (Paxillin) antibodies are designed to target and detect the Paxillin (PXN) protein, a multi-domain scaffolding protein involved in cell adhesion, motility, and signal transduction. Paxillin is a key component of focal adhesions, which are specialized structures that mediate the attachment of cells to the extracellular matrix (ECM). Through its interactions with integrins and other cytoskeletal proteins, PXN plays a critical role in regulating cellular processes such as migration, proliferation, and survival. 

Applications of PXN Antibodies

• Western Blotting (WB): PXN antibodies are used to detect paxillin in cell lysates and tissues, particularly in studies focusing on cell adhesion and migration. Western blotting allows researchers to assess the expression levels and phosphorylation status of paxillin under different experimental conditions.
• Immunohistochemistry (IHC): PXN antibodies are applied to tissue sections to visualize paxillin expression and localization, particularly in studies related to cancer, tissue remodeling, and fibrosis. IHC helps in understanding the spatial distribution of paxillin in normal and diseased tissues.
• Immunofluorescence (IF): PXN antibodies are used to stain focal adhesions and visualize the subcellular localization of paxillin in live or fixed cells. This technique is critical for studying focal adhesion dynamics, cytoskeletal reorganization, and cell migration.

PXN Antibodies in Disease Research

• Cancer Research: Paxillin is frequently overexpressed or dysregulated in various cancers, where it contributes to increased cell migration, invasion, and metastasis. PXN antibodies are used to study how paxillin promotes tumor progression through its role in focal adhesion turnover, signal transduction, and cytoskeletal reorganization. Elevated paxillin expression is often associated with poor prognosis in cancers such as breast, lung, and colorectal cancer.
• Fibrosis and Tissue Remodeling: Paxillin plays a key role in the remodeling of the ECM, making it a significant target in fibrosis research. PXN antibodies are used to investigate how paxillin influences fibroblast activity, ECM production, and tissue stiffening, which are hallmarks of fibrotic diseases.
• Wound Healing: Paxillin is crucial for proper cell migration and adhesion during wound healing processes. PXN antibodies help researchers study the role of paxillin in coordinating cellular movement and focal adhesion dynamics during tissue repair.

PXN antibodies are indispensable for studying the molecular mechanisms underlying cell adhesion, migration, and signal transduction. By enabling the detection and localization of paxillin in various experimental settings, these antibodies provide crucial insights into focal adhesion dynamics, cytoskeletal reorganization, and the role of paxillin in disease progression.
