Introduction

Osteopontin (OPN), also known as bone sialoprotein I (BSP-1 or BNSP), secreted phosphoprotein 1 (SPP1), is a human gene product. The gene has 7 exons, spans 5 kilobases in length and in humans it is located on 4q13. The protein is composed of ~300 amino acids residues and has ~30 carbohydrate residues attached including 10 sialic acid residues, which are attached to the protein during post-translational modification in the Golgi apparatus. Osteopontin has been implicated as an important factor in bone remodeling. Specifically, research suggests it plays a role in anchoring osteoclasts to the mineral matrix of bones.


Principle of the Assay  

This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-OPN polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-OPN polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the OPN amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of OPN can be calculated.
