General Description of Anti-CD279.
The J43.1 antibody is specific for mouse CD279, also known as programmed death-1 (PD-1), a 55 kDa glycoprotein which can co-regulate T cell antigen receptor signaling and therefore modulate T cell activation. PD-1 exists in a monomeric form that is expressed by CD4- CD8- thymocytes, where it participates in the processes of clonal selection, elimination of autoreactive lymphocytes, and development of tolerance. PD-1 expression is also inducible upon activation of mature T cells, where it has been proposed to interact with the co-stimulatory receptor CD80 to limit T cell activation. Two ligands for PD-1, known as PD-L1 (B7-H1) and PD-L2 (B7-DC) are differentially expressed on T and B cells, monocytes, macrophages, NK cells or dendritic cells. PD-1 is a member of a family of receptors including CD28 and CTLA-4 (CD152), which interact with B7 ligands to provide a balance of co-stimulatory /co-inhibitory signaling important in T cell activation, tolerance, and autoimmunity.The J43.1 antibody may be used as a marker for PD-1 expression, and is commonly used for analysis of receptor-ligand interaction and function(s) in vitro and in vivo. Please choose the appropriate format for each application.

Anti-CD279 Previously Observed Antibody Staining Patterns

Observed Antibody Staining Data By Tissue Type:

Variations in PD1 / PDCD1 / CD279 antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in germinal center cells in the tonsil. More moderate antibody staining intensity was present in germinal center cells in the tonsil. Low, but measureable presence of PD1 / PDCD1 / CD279 could be seen in cells in the red pulp in spleen. We were unable to detect PD1 / PDCD1 / CD279 in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.
