Recombinant Human CD86 Protein (Leu20-His239), C-hFc-tagged
Product Description
Cat
IMP-10305
Official Symbol
CD86
Product Overview
Recombinant human B7-2/CD86 protein (Leu20-His239) with a Human IgG1 (Pro100-Lys330) Fc tag C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.
