Product Summary for Human SHBG Quantikine ELISA Kit

The Quantikine® Human SHBG Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human SHBG in cell culture supernates, serum, and  plasma. It contains NS0-expressed recombinant human SHBG and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human SHBG showed linear curves that were parallel to the standard curves obtained using the Quantikine® kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human SHBG.

Quantitative ELISA

Detection Method

Colorimetric - 450nm (TMB)






Natural and recombinant human SHBG.


< 0.5% cross-reactivity observed with available related molecules. < 50% cross-species reactivity observed with species tested.


No significant interference observed with available related molecules.


Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using one lot of components.

Recovery for Human SHBG Quantikine ELISA Kit

The recovery of human SHBG spiked to levels throughout the range of the assay was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 92 87-96


To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human SHBG were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

Background: SHBG

SHBG (Sex Hormone-binding Globulin), also known as ABP (Androgen-binding Protein), is a variably glycosylated, secreted, non-disulfide-linked homodimer. Male and female sex hormones bind SHBG with equal affinity. This binding protein can be found in the circulation where it regulates hormone access to target tissues. Human SHBG shares approximately 67% amino acid sequence identity with mouse and rat SHBG.
