  • Tested application: ELISA
    Test sample: Serum
    Species: Human
    Review:Used this kit to test a variety of serum samples. Instructions were easy to follow and sufficient reagent is provided to test a variety of conditions. I wish i had more info on the standard used in the kit so it could easily be compared to other vendor protein options tested! Overall impressed with the packaging and ease of use.

靶点详情

  • 功能：
    Cytokine which is the ligand for CD27. The CD70-CD27 pathway plays an important role in the generation and maintenance of T cell immunity, in particular during antiviral responses. Upon CD27 binding, induces the proliferation of costimulated T-cells and enhances the generation of cytolytic T-cells.
