  • Product overview

    Abcam’s Fas Ligand (Fas-L) Human in vitro ELISA Set is designed for the quantitative measurement of Fas-L in cell culture supernatants, buffered solutions, serum, plasma and other body fluids.


    The Fas L ELISA Set includes both the capture and the detection antibodies as well as Horse-Radish peroxidase conjugated Streptavidin (HRP-Strep) and TMB which are the reagents used in the colour development step.


    This ELISA Set is intended to measure Fas L in cell -culture supernatants, as well as in serum samples. The enclosed procedures provide general guidelines for ELISA preparation. This procedure may need some optimization depending on the plastic, matrix, standard range.


    SPECIFICITY: Recognizes both natural and recombinant soluble human Fas-Ligand RANGE: 62.5pg/ml - 2000pg/ml SENSITIVITY: <12pg/ml

  • Research areas
  • Relevance
    Fas / APO1 (CD95) is an important member of the tumour necrosis factor (TNF) superfamily involved in membrane mediated apoptosis. Ligation of Fas by Fas Ligand or an anti Fas cross linking antibody, triggers activation of the caspase cascade. Functional impairment of the Fas / Fas Ligand system is associated with the development and progression of malignancies. Fas gene mutations have been suggested to have a role in testicular germ cell tumors. Tumor cells frequently exhibit de novo expression of Fas Ligand, which plays a significant role in local tissue destruction, metastatic spread, and immune escape of the tumor cells. The apoptosis of lymphocytes, which occurs in autoimmune diseases, is usually induced by the Fas/Fas Ligand system. The full length of FasL contains 281 amino acids, consisting of the transmembrane domain, extracellular domain, and the cytoplasmic region. A metalloproteinase cleaves the membrane-bound FasL to produce soluble Fas (sFasL), which exists as a homotrimer. The sFasL shows lower cytotoxicity than membrane bound FasL.
