Anti-STMN4 Antibody

This rabbit polyclonal IgG antibody from Antibodies.com targets STMN4 (Stathmin-like 4, also called RB3), a neuronal-enriched member of the stathmin family of microtubule-destabilizing phosphoproteins. STMN4 is expressed predominantly in the central nervous system, where it regulates microtubule dynamics and has been implicated in neurite extension, axon guidance, and neuronal differentiation.

The reagent is supplied as 50 µl of unconjugated polyclonal antiserum raised in rabbit, validated for Western blot (WB) detection of endogenous STMN4 in mouse and rat samples. Because it is unconjugated, the antibody functions as a primary reagent for use with researcher-selected secondary antibodies and detection chemistries. Recommended handling includes brief centrifugation of the vial prior to opening, storage at -20 °C in working aliquots to limit freeze-thaw cycles, and protection from light when applied in downstream fluorescence or chemiluminescence workflows.

Reactivity is restricted to Mouse and Rat species. Investigators studying neuronal development, microtubule cytoskeleton remodeling, or phospho-regulation of stathmin-family proteins in rodent brain and nervous tissue commonly employ this antibody to probe STMN4 expression by Western blot.
