Product Overview
This rabbit polyclonal antibody recognizes cell division control protein 42 homolog (gene CDC42) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 21.3 kDa, and the supplier reports an observed band at about 21 kDa.
CDC42 is a Rho family small GTPase that cycles between active GTP-bound and inactive GDP-bound states. In its active form it engages effectors such as PAK and WASP to control actin organization, filopodia formation, cell polarity and migration, making it a central regulator in cytoskeletal and polarity research.

Immunogen
Recombinant human CDC42 fragment (Asn26–Leu191), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places cell division control protein 42 homolog in the cell membrane, cytoplasm and midbody. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
