  • Product overview

    Abcam’s Perforin (PRF1) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Perforin in supernatant and buffered solutions.

    A monoclonal antibody specific for Perforin has been coated onto the wells of the microtiter strips provided. Samples, including standards of known Perforin concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for Perforin are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of Perforin present in the samples. 

    This kit will recognize both endogenous and recombinant Human Perforin.

  • PlatformMicroplate


  • FunctionPlays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Plays an important role in killing other cells that are recognized as non-self by the immune system, e.g. in transplant rejection or some forms of autoimmune disease. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes.
  • Involvement in diseaseFamilial hemophagocytic lymphohistiocytosis 2
  • Sequence similaritiesBelongs to the complement C6/C7/C8/C9 family.
    Contains 1 C2 domain.
    Contains 1 EGF-like domain.
    Contains 1 MACPF domain.
  • DomainThe C2 domain mediates calcium-dependent binding to lipid membranes. A subsequent conformation change leads to membrane insertion of beta-hairpin structures and pore formation. The pore is formed by transmembrane beta-strands.
  • Post-translational
  • Cellular localizationCytoplasmic granule lumen. Secreted. Cell membrane. Endosome lumen. Stored in cytoplasmic granules of cytolytic T-lymphocytes and secreted into the cleft between T-lymphocyte and target cell. Inserts into the cell membrane of target cells and forms pores. Membrane insertion and pore formation requires a major conformation change. May be taken up via endocytosis involving clathrin-coated vesicles and accumulate in a first time in large early endosomes.

Das stimmt tatsächlich so, wie es im Protokoll steht: Auspacken, und losexperimentieren!

Ich wünsche Ihnen viel Erfolg mit Ihren Versuchen!

Der Puffer ist Gebrauchsfertig! Wir werden unser Datenblatt dem entsprechend aendern.

Thank you for your response.   I would like to clarify that the kit batch we currently have in stock does contain standards vials 3060 pg/vial.   The following standards batch (1820 pg/vial) will be included in the next kit batch production p...
