Product overview
Human Vitronectin/S-Protein ELISA Kit (ab234577) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Vitronectin/S-Protein protein in serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Vitronectin/S-Protein with 19.9 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Function
Vitronectin is a cell adhesion and spreading factor found in serum and tissues. Vitronectin interact with glycosaminoglycans and proteoglycans. Is recognized by certain members of the integrin family and serves as a cell-to-substrate adhesion molecule. Inhibitor of the membrane-damaging effect of the terminal cytolytic complement pathway.
Somatomedin-B is a growth hormone-dependent serum factor with protease-inhibiting activity. -
Tissue specificity
Plasma. -
Sequence similarities
Contains 4 hemopexin repeats.
Contains 1 SMB (somatomedin-B) domain. -
Domain
The SMB domain mediates interaction with SERPINE1/PAI1. The heparin-binding domain mediates interaction with insulin. -
Post-translational
modificationsSulfated on 2 tyrosine residues.
N- and O-glycosylated.
Phosphorylation on Thr-69 and Thr-76 favors cell adhesion and spreading.
It has been suggested that the active SMB domain may be permitted considerable disulfide bond heterogeneity or variability, thus two alternate disulfide patterns based on 3D structures are described with 1 disulfide bond conserved in both.
Phosphorylation sites are present in the extracellular medium. -

SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

Example of human Vitronectin standard curve in 1X Cell Extraction Buffer PTR.The Vitronectin standard curve was prepared as described in Section 10.
-
Interpolated concentrations of native Vitronectin in human serum samples.The concentrations of Vitronectin were measured in duplicates, interpolated from the Vitronectin standard curves and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Vitronectin concentration was determined to be 234.2 µg/mL in serum.
