U-Blot® Recombinant CD32 (VF0032) Fc-Fused Nanobody

Background：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 ofThis protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding ofThis 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.[provided by RefSeq, May 2011]
