Anti-ALB Antibody

This rabbit polyclonal antibody specifically recognizes human serum albumin (ALB), a 66.5 kDa circulating protein synthesized by hepatocytes that maintains oncotic pressure and serves as a carrier for endogenous and exogenous ligands. From Antibodies.com, the reagent is supplied in a vial containing 100 µl of unconjugated antibody, enabling researchers to pair it with their preferred secondary detection system for maximum experimental flexibility.

Validated for Western blot (WB) and immunohistochemistry (IHC) applications, the polyclonal format allows multi-epitope recognition of the target. Albumin detection is widely used in studies of hepatic synthetic function, nephrotic syndrome and protein-losing kidney disease, acute-phase response, burn trauma and critical care, as well as gastrointestinal disorders such as protein-losing enteropathy. In addition, ALB immunoblotting commonly serves as a loading control for normalizing signals against a highly abundant, constitutively expressed protein.

For storage, aliquot upon receipt and store at -20 °C in working volumes to limit freeze-thaw cycles; the antibody remains stable for short-term use at 4 °C. The unconjugated format means end users select their own HRP, biotin, or alkaline phosphatase conjugates tailored to their Western blot membrane or IHC chromogen system.
