Product Description
The protein encoded by human CD276 gene belongs to the immunoglobulin superfamily, and thought to participate in the regulation of T-cell-mediated immune response. Studies show that while the transcript of this gene is ubiquitously expressed in normal tissues and solid tumors, the protein is preferentially expressed only in tumor tissues. Additionally, it was observed that the 3′ UTR of this transcript contains a target site for miR29 microRNA, and there is an inverse correlation between the expression of this protein and miR29 levels, suggesting regulation of expression of this gene product by miR29.
Full-length extracellular domain of human CD276 gene (29 – 466 aa) was constructed with 29 N-terminal T7/His tag and expressed in E. coli as inclusion bodies.
The final product was refolded using a unique “temperature shift inclusion body refolding” technology and chromatographically purified.

Directions for Use

Use these recommendations as guidelines to determine the optimal coating conditions for your culture system.
- Thaw CD276 and dilute to desired concentration using serum-free medium or PBS. The final solutionshould be sufficiently dilute so that the volume added covers the surface evenly. Note: Use 1 ml PBS perwell in a 6-well plate.
- Add 1 – 10 µg protein to each well and incubate at 2 to 10°C overnight.
- After incubation, aspirate remaining material.
- Plates are ready for use. They may also be stored at 2-8°C damp or air dried if sterility is maintained.
Coating this recombinant protein at 1-10 ug / well (6 well plate) in T cell specific medium can be used 1) for human T cell / receptor interaction studyin vitroor 2) as a highly purified recombinant antigen as cancer biomarker for diagnosis application development.
