Anti-Prealbumin Antibody

The Antibodies.com anti-prealbumin polyclonal reagent is raised in rabbit and supplied as a 100 µg liquid aliquot in a single vial, ready for western blot workflows on human samples. Prealbumin, also known as transthyretin (TTR), is a ~55 kDa homotetrameric protein that binds thyroxine and circulates as a complex with retinol-binding protein; it is widely studied as a marker of nutritional status, hepatic synthetic function, and the amyloidogenic mutations linked to familial amyloid polyneuropathy and senile systemic amyloidosis. The unconjugated IgG format allows flexible pairing with HRP, fluorescent, or biotin-labelled secondary detection reagents depending on the western blot protocol. For best stability, store the antibody refrigerated at 4 °C in single-use aliquots to limit freeze-thaw cycles, and protect from prolonged light exposure. Intended for research use only in studies of thyroxine transport, vitamin A metabolism, and TTR-related amyloidosis models.
