spectrin β II Antibody (F-11) is a mouse monoclonal IgG1 antibody that detects spectrin β II in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). Spectrin β II plays a crucial role in maintaining the structural integrity and organization of the cytoskeleton, particularly in non-erythroid cells, where spectrin β II contributes to the dynamic organization of the plasma membrane and facilitates cellular processes such as secretion. Spectrin β II interacts with calmodulin in a calcium-dependent manner, which is essential for the regulation of cytoskeletal movement at the membrane, highlighting spectrin β II′s importance in cellular signaling and function. The human SPTBN1 gene encodes the nonerythroid form of β-spectrin, and spectrin β II′s proper functioning is vital for various cellular activities, including maintaining cell shape and enabling cellular communication. Anti-spectrin β II antibody (F-11) is an invaluable tool for researchers studying cytoskeletal dynamics and related cellular processes across different species.
