Anti-CBG Antibody

Raised in rabbit against human corticosteroid-binding globulin (transcortin, SERPINA6), this unconjugated polyclonal primary antibody from Antibodies.com targets the ~50 kDa hepatic glycoprotein that sequesters roughly 90% of circulating cortisol and also binds progesterone, aldosterone, and other steroid ligands.

Supplied as a 100 µl aliquot in a vial, the reagent is validated for western blot and ELISA workflows on human samples, supporting studies of HPA-axis regulation, glucocorticoid transport, hepatic protein expression, and SERPINA6 deficiency. The polyclonal format presents multiple epitopes across the target, which is useful when probing denatured lysates on membranes or capturing native protein in plate-based assays.

Because the antibody is unconjugated and the host is rabbit, it pairs cleanly with anti-rabbit HRP or fluorophore secondaries and fits standard chromogenic and chemiluminescent detection pipelines. Store refrigerated at 4 °C and avoid repeated freeze-thaw cycles to preserve titer; aliquot upon first thaw if working in small batches.
