Product Summary
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 ocurring SHBG.

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 separate assays to assess inter-assay precision.

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of SHBG were serially diluted with Calibrator Diluent RD5-24 (1:15) to produce samples with values within the dynamic range of the assay.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.
