Anti-SMPX Antibody

SMPX (Small Muscle Protein X-linked) encodes a cytoskeletal protein critical to striated muscle integrity and auditory hair cell function in the inner ear. This unconjugated polyclonal reagent from Antibodies.com was raised in rabbit and affinity-purified to deliver selective recognition of endogenous SMPX in human, mouse, and rat samples.

The antibody is supplied as 100 µl of liquid (IgG isotype), validated for western blot and immunofluorescence workflows. Investigators studying DFNX4 hearing loss, cardiomyopathy models, or skeletal muscle regeneration rely on SMPX antibodies to localize the protein at costameric and intercalated disc regions. Aliquot on arrival to limit freeze-thaw cycles, store at -20 degrees C, and protect from light for long-term stability.

The unconjugated format supports flexible pairing with secondary reagents of the researcher's choice, including HRP, Alexa Fluor, or biotin conjugates. Compatible sample types include cultured myocytes, cardiac tissue sections, skeletal muscle lysates, and cochlear preparations where the X-linked inheritance pattern of SMPX-linked deafness makes species cross-reactivity across human, mouse, and rat especially valuable.
