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 Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Biotinylated Human B7-2, Fc,Avitag on SDS-PAGE under reducing (R) and non-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 Biotinylated Human B7-2, Fc,Avitag (Cat. No. CD6-H82F5) can bind to CD28 expressed on Jurkat E6.1 cells. The concentration of B7-2 used is 1.5 μg/mL (Routinely tested).
FACS analysis shows that the binding of Biotinylated Human B7-2, Fc,Avitag to CD28 expressed on Jurkat E6.1 was inhibited by increasing concentration of neutralizing Anti-CD28 antibody. The concentration of B7-2 used is 1.5 μg/mL. The IC50 is 0.031 μg/mL (Routinely tested).
Flow Cytometry assay shows that Biotinylated Human B7-2, Fc,Avitag (Cat. No. CD6-H82F5) can bind to 293 cell overexpressing human CTLA-4. The concentration of Human B7-2 is 2 μg/mL (Routinely tested).
FACS analysis shows that the binding of Biotinylated Human B7-2, Fc,Avitag (Cat. No. CD6-H82F5) to 293 overexpressing CTLA-4 was inhibited by increasing concentration of neutralizing Anti-human CTLA-4 antibody. The concentration of Human B7-2 is 2 μg /mL. The IC50 is 1.014 μg/mL (Routinely tested).
