>Biotinylated Human B7-2 / CD86 / CD28 Ligand 2 Protein, Fc Tag, Avi Tag
This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).
The protein has a calculated MW of 53.8 kDa. As a result of glycosylation, the protein migrates as 66-100 kDa under reducing (R) condition, and 120-140 kDa under non-reducing (NR) condition (SDS-PAGE).
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

No activity loss is observed after storage at:
Biotinylated Human B7-2, Fc Tag on SDS-PAGE under reducing (R) and no-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Flow Cytometry assay shows that recombinant Biotinylated Human B7-2 / CD86 Protein, Fc Tag, Avi Tag (Cat. No. CD6-H82F5) can bind to CD28 expressed on Jurkat E6.1 cells. The concentration of CD86 used is 1.5ug/ml (Routinely tested).
FACS analysis shows that the binding of CD86 to CD28 expressed on Jurkat E6.1 was inhibited by increasing concentration of neutralizing anti-CD28 antibody. The concentration of CD86 used is 1.5ug/ml. The IC50 is 0.031 ug/ml (Routinely tested).
The Biotin AviTag technology is covered by U.S. Pat. No: 5,874,239 and includes any and all materials, methods, kits and related derivatives claimed by this patent. The purchase of the Acrobiosystems’s Avitag™ proteins confers to the purchaser the limited right to use the Avitag™ technology for non-commercial, or research use, or for purposes of evaluating the Avitag™ technology.
Commercial use of the Avitag™ technology to manufacture a commercial product, or use of the Avitag™ technology to facilitate or advance research which will be applied to the development of a commercial product requires a license from Avidity, LLC. Examples of Commercial use include, but are not limited to biosensors, diagnostics, therapeutic applications, proximity assays, and drug screening assays.
