Biological Activity

Description

Osteopontin/OPN Protein, a key non-collagenous bone protein, strongly binds to hydroxyapatite, crucial for the mineralized matrix.It likely plays a vital role in mediating cell-extracellular matrix interactions.Additionally, as a cytokine, OPN stimulates interferon-gamma and interleukin-12 production, while inhibiting interleukin-10, pivotal for the type I immunity pathway.Osteopontin/OPN Protein, Rat (CHO, His) is the recombinant rat-derived Osteopontin/OPN protein, expressed by CHO , with C-6*His labeled tag.

Background

Osteopontin (OPN) protein, a significant non-collagenous bone protein, tightly binds to hydroxyapatite and plays a crucial role in the mineralized matrix. It is likely essential for facilitating interactions between cells and the extracellular matrix. Furthermore, OPN acts as a cytokine, promoting the production of interferon-gamma and interleukin-12, while inhibiting the production of interleukin-10. These functions are vital in the pathway that leads to type I immunity.

Verified Bioactivity

Measured by the ability of the immobilized protein to support the adhesion of HEK293 human embryonic kidney cells. When 1 x 105 cells/well are added to Recombinant Rat Osteopontin/OPN coated plates, cell adhesion is enhanced in a dose dependent manner after 1 hour incubation at 37°C. The ED50 for this effect is < 1.50 µg/mL.

Formulation

1.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Please refer to the lot-specific COA for specific buffer information.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
