B7-2/CD86 Protein, Human (HEK293, Fc)
Based on 1 Customer Validation
B7-2/CD86 Protein, Human (HEK293, Fc) is a polypeptide chain with the C-termimal human IgG1 Fc fragment 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.
- Species: Human
- Source: HEK293

Description
B7-2/CD86 Protein, Human (HEK293, Fc) is a polypeptide chain with the C-termimal human IgG1 Fc fragment 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.
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].
Verified Bioactivity
Immobilized B7-2/CD86-Fc at 5 μg/mL (100 μL/well) can bind human Biotin-CD28-Fc with a linear range of 0.09~3.12μg/mL.
