Anti-BFSP1 Antibody

This rabbit polyclonal antibody from Antibodies.com targets BFSP1, also known as filensin, a beaded filament structural protein that builds the specialized cytoskeletal framework of ocular lens fiber cells. The unconjugated IgG reagent is provided as a 100 µl volume and is validated for western blot detection across human, mouse, and rat samples. BFSP1 heteropolymerizes with phakinin (BFSP2/CP49) to assemble the beaded filament network that maintains lens transparency and optical clarity, so this reagent is commonly used by groups studying congenital cataract mutations, lens fiber cell differentiation, and intermediate filament organization in the vertebrate eye. Its polyclonal format allows recognition of multiple epitopes on the filensin target, which can be helpful when probing expression in lens epithelium and fiber cell extracts, as well as in tissue lysates from rodent models of hereditary cataract. Supplied as a single-use vial suitable for research use only, the antibody supports reproducible immunoblotting workflows and pairs well with anti-rabbit secondary reagents for chemiluminescent or colorimetric readout.
