Description

Recombinant Protein

PeproTech's CHO cell-derived Recombinant Human B7-H2 Fc is a glycosylated, disulfide-linked homodimer of 942 amino acid residues whose monomer consists of the 238-amino-acid length extracellular portion of B7-H2 fused to the 231-amino-acid length Fc portion of human IgG1 by two glycines. The calculated molecular weight of Recombinant Human B7-H2 Fc dimer is 104.9 kDa; however, due to glycosylation, it migrates at an apparent molecular weight of approximately 90-95 kDa by SDS-PAGE analysis under reducing conditions. This product is shipped at ambient temperature. For storage, handling and reconstitution information, please see the lot-specific Certificate of Analysis

Inducible co-stimulator ligand (ICOSL) is a specific ligand on antigen-presenting cells and cells of the peripheral tissue that binds to the inducible co-stimulator receptor (ICOS). ICOS belongs to the CD28/CD152 receptor family that regulates T-cell activation and function. ICOSL is expressed on monocytes, dendritic cells and B cells and can be induced by inflammatory stimuli in peripheral tissue. Binding to ICOSL delivers a co-stimulatory signal for T cell proliferation and cytokine secretion.
