  Detection of PDL1 neutralizing antibody using MACS column. GFP+/PDL1+ 293T cells (co-transfected with PDL1 and GFP plasmid (RC213071, PS10010) were incubated with either PDL1 antibody TA813015, Avelumab (right), negative control antibody (middle) or PBS (left) and then mixed with PD1+ 293T cells (RC210364) linked with magnetic-beads. The mixed cells were pulled down using MACS column (Miltenyi Biotec) and analysed by Flow Cytometry. GFP+/PDL1+ cells would not be collected if PD1/PDL1 interaction is neutralized by the tested antibody (1:50).

• Background: This gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells. The encoded protein is a type I transmembrane protein that has immunoglobulin V-like and C-like domains. Interaction of this ligand with its receptor inhibits T-cell activation and cytokine production. During infection or inflammation of normal tissue, this interaction is important for preventing autoimmunity by maintaining homeostasis of the immune response. In tumor microenvironments, this interaction provides an immune escape for tumor cells through cytotoxic T-cell inactivation. Expression of this gene in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]
