Anti-PAX7 Antibody

PAX7 (Paired Box 7) is a key transcription factor that regulates the specification and maintenance of skeletal muscle satellite cells, the resident stem cell population responsible for postnatal muscle growth and regeneration. This unconjugated rabbit polyclonal reagent from Antibodies.com targets the human PAX7 protein and is validated for Western blot and immunohistochemistry workflows. The antibody is supplied as 100 µl of a 1 mg/ml stock in PBS containing 0.1% sodium azide and 50% glycerol as a cryoprotectant, allowing convenient refrigerated storage and resistance to repeated freeze-thaw cycles. In skeletal muscle research, PAX7 immunostaining is widely used to identify and quantify satellite cells in tissue sections, while Western blot detection supports studies of muscle stem cell activation, myogenic differentiation, and satellite cell self-renewal. The reagent is reactive with human samples and remains unconjugated, giving researchers flexibility to pair it with secondary antibodies of their choice for chromogenic or fluorescence-based detection platforms. Rhabdomyosarcoma and congenital muscular dystrophy investigations also benefit from reliable PAX7 labelling, because the protein's expression pattern is characteristically altered in these myogenic disorders and is frequently used as a diagnostic marker in pathology laboratories.
