B7-2/CD86 Protein, Human (HEK293, Fc-His)

Cat. No.: HY-P7323
Handling Instructions

B7-2/CD86 Protein, Human (HEK293, Fc-His) is a polypeptide chain with the C-termimal human Fc-His Tag produced in HEK293 cells. B7-2 (CD86) is a costimulatory molecule expressed by antigen-presenting cells (APCs), which interacts with CD28 for T-cell activation and survival and with CTLA4 for immune regulation.

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

Endotoxin Level

<0.1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O or PBS.

Storage & Stability

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.


Room temperature in continental US; may vary elsewhere.


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].
