Biological Activity
5 µg/mL (100 µL/well) of immoblized recombinant human B7-2/CD86-Fc can bind human Biotin-CD28-Fc with a linear range of 0.09-3.12 μg/mL.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against PBS, 5% trehalose and mannitol.

Endotoxin Level
<0.2 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human B7-2/CD86, Fc Chimera (HEK293-expressed) (rHuB7-2/CD86, Fc Chimera) to 100 µg/mL using ddH2O or diluted with PBS.

Storage & Stability
Lyophilized recombinant Human B7-2/CD86, Fc Chimera (HEK293-expressed) (rHuB7-2/CD86, Fc Chimera) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
CD86 is a transmembrane region, and a longer cytoplasmic domain than CD80. CD86 is constitutively expressed on interdigitating dendritic cells (DCs), Langerhans cells, peripheral blood DCs, memory B cells and germinal center B cells, and macrophages. CD86 is rapidly upregulated on B cells following activation by cross-linking of the Ig receptor or the addition of a variety of cytokines[1].
