Product Overview
This rabbit polyclonal antibody targets twinfilin-2 (gene TWF2) in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 39.5 kDa, and the supplier reports an observed band at about 40 kDa.
Twinfilin-2 (TWF2) is an actin monomer-binding protein related to twinfilin-1. It limits actin polymerization and regulates filament barbed ends, influencing cell motility and endocytosis, and it has been reported to help set the length of stereocilia in inner ear hair cells.

Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (ICC/IF): HeLa cells.
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Recombinant human TWF2 fragment (Leu13–Lys327), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places twinfilin-2 in the cytoplasm and cell projection. Tissue expression noted by UniProt (human): Ubiquitously expressed (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
