Human Corticosteroid Binding Globulin (CBG) ELISA Kit

The Assay Genie CBG kit quantifies Corticosteroid Binding Globulin, a 56 kDa glycoprotein (encoded by SERPINA6) also known as transcortin, which is synthesized in hepatocytes and serves as the principal plasma carrier of glucocorticoids including cortisol. CBG measurements support research in endocrinology, stress axis biology, inflammatory signaling, hepatic function, and reproductive endocrinology, where circulating CBG levels influence free cortisol fractions and downstream glucocorticoid activity.

The microplate-based quantitative immunoassay uses a chromogenic read-out compatible with standard laboratory plate readers. Workflow involves binding, incubation, washing, and detection steps. Each kit includes a pre-coated microplate, assay diluent, detection reagent, standard, and substrate.

Store unopened kit components refrigerated at 4 degrees C. Reconstituted standards and detection reagent should be aliquoted and stored frozen to limit freeze-thaw cycles; allow all reagents to equilibrate to room temperature before use.
