Anti-STAR Antibody

Raised in rabbit against the Steroidogenic Acute Regulatory Protein (STAR), this polyclonal antibody from Antibodies.com supports detection of the mitochondrial cholesterol transporter that drives the rate-limiting step of steroid hormone biosynthesis. The reagent has been validated for Western blot and immunohistochemistry workflows on human, mouse, and rat samples, covering adrenal cortex, gonadal, and placental tissue sections where steroidogenesis is most active.

Supplied as 100 µl of liquid at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant, the unconjugated antibody can be used directly in immunostaining and immunoblotting or conjugated downstream for custom detection schemes. Recommended storage is at -20 °C in working aliquots to limit freeze-thaw cycles, with the sodium azide preserving microbial stability during routine bench use. Researchers investigating congenital lipoid adrenal hyperplasia, Leydig cell steroid output, trophoblast hormone production, or stress-driven cortisol regulation can apply this reagent to track STAR expression, 30 kDa precursor processing, and mitochondrial translocation in steroidogenic cells.
