• Reactivity: Reacts with: Mouse, Rat; N.B. Antibody reactivity and working conditions may vary between species.
• Applications: Immunohistochemistry, Western Blot
• Synonyms: CD274; Polyclonal Antibody; RABBIT ANTI HUMAN CD274; anti-CD274 antibody

• Host: Rabbit
• Reactivity: Reacts with: Mouse, Rat; N.B. Antibody reactivity and working conditions may vary between species.
• Clonality: Polyclonal
• Isotype: IgG
• Specificity: This item detects CD274, also known as B7-H1 and PD-1L, a cell surface glycoprotein which is a member of the B7 family of co-stimulatory molecules. CD274 is expressed constitutively on macrophages and dendritic cells, and is induced on activated T-cells, B-cells, endothelial cells and epithelial cells in response to Interferons alpha, beta and gamma. ; ; CD274 is reported to possess dual functions; inhibition of activated effector T cells and co-stimulation of naïve T cells. CD274 inhibits proliferation of activated T cells via ligation to the co-inhibitory molecule CD279 (programmed death-1; PD-1) leading to the secretion of the regulatory cytokine interleukin-10. CD274 has also been shown to co-stimulate early T cell priming and differentiation. ; ; Deregulated CD274 function has been reported in chronic viral and intracellular bacterial infection, as well as in many autoimmune diseases and cancers.

Uniprot Description

CD274: Involved in the costimulatory signal, essential for T- cell proliferation and production of IL10 and IFNG, in an IL2- dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production. Belongs to the immunoglobulin superfamily. BTN/MOG family. 3 isoforms of the human protein are produced by alternative splicing.
