Product Summary for Human Vitamin D BP Quantikine ELISA Kit

The Quantikine® Human Vitamin D BP immunoassay is a 3.5 hour sandwich-type solid phase ELISA designed to measure human Vitamin D BP in cell culture supernates, serum, plasma, and urine. It contains HEK293-expressed recombinant human Vitamin D BP and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Vitamin D BP 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 natural human Vitamin D BP.

Precision

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 two lots of components.

Urine (n=4) 89 78-96

Linearity

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

Background: Vitamin D BP

Vitamin D binding protein (VitD BP), also known as DBP and Gc-globulin, is a 58 kDa glycoprotein that circulates at high concentration in the serum and serves as a carrier protein for vitamin D. The transport of vitamin D by VitD BP is important for the function of a wide variety of tissues. VitD BP binds both the 25(OH) and the hormonally active 1,25(OH)2 forms of vitamin D. VitD BP is primarily expressed in hepatocytes and to a lesser extent in the kidney. It delivers vitamin D into cells by Megalin-mediated endocytosis. A selectively deglycosylated form of VitD BP known as macrophage activating factor (MAF) blocks the angiogenic effects of FGF basic, VEGF, and Angiopoietin 2. VitD BP enhances the chemotaxis of monocytes and neutrophils to the activated complement component C5a or C5a des Arg (a C-terminally processed form of C5a). The chemotactic cofactor property of VitD BP is eliminated by binding to 1,25(OH)2 vitamin D, but it is not altered by binding to 25(OH) vitamin D or actin.
