Immunohistochemical analysis of paraffin-embedded Human lung cancer tissues using CD274 antibody with DAB staining.Pre-treat the sections with heat-mediated antigen retrieval using sodium citrate buffer (pH 6.0) (OM750020) for 2 minutes. Wash the sections with ddH₂O and PBS (OM750003). Block the tissue with 10% non-immune goat serum(OM760028) at room temperature for 30 minutes. Incubate the tissue with the primary antibody diluted at a ratio of 1:1500 at 4°C overnight. At room temperature, dilute the secondary antibody, Goat Anti-Rabbit IgG(H&L)-HRP (OM643487), at a ratio of 1:200 and incubate for one hour. Use DAB(OM760029)as the chromogenic agent. Counterstain the tissue with hematoxylin, and mount the tissue sections with neutral gum.IHC

Immunofluorescence analysis of U251 cells using CD274 antibody (green). Blue: DAPI fluorescent DNA dye. Red: Actin filaments have been labeled with Omnimabs® 594-Phalloidin.Cells are fixed in 4% paraformaldehyde at room temperature for 20 minutes. Then, they are permeabilized with a PBS (OM750003) solution containing 0.1% Triton X-100(OM750021) at room temperature for 15 minutes. Subsequently, the cells are blocked with 10% non - immune goat serum(OM760028) at room temperature for 1 hour.The cells are incubated overnight at 4°C with the primary antibody diluted 1:100 in PBS. The secondary antibody, Omnimabs® 488 Goat Ant-Rabbit IgG(H&L) (Green,OM643486), is diluted at a ratio of 1:400 and incubated with the cells for 1 hour.Nuclear DNA is labeled with DAPI (Blue,OM643160). F-actin is stained with Omnimabs® 594-Phalloidin (Red,OM750007) diluted 1:100 for 30 minutes.IHC

| Gene Summary | 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] |
