  • Tested applicationsSuitable for: Flow Cytmore details
  • Species reactivity
    Reacts with: Mouse
  • Immunogen

    Syrian Hamster kidney cell line BKH transfected with Mouse PD1 cDNA.

  • General notes

    It is reported that monoclonal antibody J43 inhibits the binding of mouse PD-L1-Ig and mouse PD-L2-Ig to PD-1/BHK transfected cells. When administrated in vivo, both intact and Fab of J43 are reported to enhance contact hypersensitivity and exacerbate acute GVHD similar to transfer of PD-1-deficient cells. Injection of J43 also exacerbates EAE and NOD diabetes as do specific antibodies to mouse PD-L1 and PD-L2.



Our Abpromise guarantee covers the use of ab95789 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Flow Cyt Use 0.25-0.5µg for 105 cells. Cell number should be determined empirically but can range from 105 to 108 cells/test (based on a test volume of 100 µl).

ab18479-Armenian Hamster monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • FunctionPossible cell death inducer, in association with other factors.
  • Involvement in diseaseGenetic variation in PDCD1 is associated with susceptibility to systemic lupus erythematosus type 2 (SLEB2) [MIM:605218]. Systemic lupus erythematosus is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system.
  • Sequence similaritiesContains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Developmental stageInduced at programmed cell death.
