Description
Anti-Human Fibulin-4 [5G11] In Vivo Antibody - Low Endotoxin
Introducing the Anti-Human Fibulin-4 [5G11] In Vivo Antibody - Low Endotoxin from Assay Genie, a highly specific monoclonal antibody designed for in vivo applications. This antibody targets the Fibulin-4 protein, a critical component in elastic fiber formation and extracellular matrix stabilization, ideal for research in cardiovascular development, connective tissue disorders, and related fields. With a mouse IgG1 isotype, it ensures high purity and low endotoxin levels (<1.0 EU/mg), perfect for ELISA, flow cytometry, immunohistochemistry, and other assays. Available in various sizes, it is formulated in phosphate-buffered saline for stability and efficacy.
Enhance your research with this reliable and versatile antibody. Fibulin-4 is a 55 kDa glycoprotein that plays a significant role in the assembly of elastic fibers and the maintenance of extracellular matrix integrity. It is essential for proper cardiovascular development and is linked to diseases such as cutis laxa and aneurysms when mutated. The study of Fibulin-4 is crucial for understanding the underlying mechanisms of connective tissue disorders. ---

There are currently seven genes in the fibulin family (Fibulin-1, 2, 3, 4, 5, 6, and 7) that are associated with elastic fibers. The fibulins are widely distributed throughout the body and are more prominent in tissues rich in elastic fibers and are often associated with vasculature and elastic tissues. Fibulin-4 appears to be the most critical member of this family of proteins in modulating elastic-fiber formation because studies have shown that fibulin-4-null mice do not produce elastic fibers at all.1 This extracellular glycoprotein has a molecular weight of approximately 49 kD, and is not only considered a structural protein of the extracellular matrix, but also a regulatory factor required for normal elastin expression in human fibroblasts.2 Due to the regulatory role of Fibulin-4, it is thought that a pathophysiological link may exist between the modulation of fibulin-4 levels and diseases, such as WBS (Williams-Beuren syndrome), that are characterized by impaired elastic-fiber formation.1 Furthermore, fibulin-4 has been shown to interact with P53, a crucial homologous protein that prevents cancer formation, and thus functions as a tumor suppressor.3 One study indicated that colon tumors were found to have approximately 2-7-fold increases of fibulin-4 mRNA expression. This suggests that the dysregulated expression of the fibulin-4 gene is associated with human colon tumourigenesis.4
