CD178 (Fas Ligand) Monoclonal Antibody (MFL3), PE-Cyanine7, eBioscience™, Invitrogen™

Description

• Description: The MFL3 monoclonal antibody reacts with mouse Fas (CD95) Ligand, a 40 kDa type II transmembrane glycoprotein
• FasL is a member of the TNF family and is expressed by mouse activated T cells
• The interaction of FasL with its receptor CD95 induces Fas-mediated killing
• It has been reported that the human FasL antigen is cleaved from the surface by matrix metalloproteinases (MMPs), resulting in a 26 kDa soluble form
• The degree of sensitivity for the mouse antigen to MMPs has not been reported
• Applications Reported: This MFL3 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This MFL3 antibody has been tested by flow cytometric analysis of transfected cells
• This can be used at less than or equal to 0.5 μg per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest
• Light sensitivity: This tandem dye is sensitive photo-induced oxidation
• Please protect this vial and stained samples from light
• Fixation: Samples can be stored in IC Fixation Buffer (cat
• 00-8222) (100 μL cell sample + 100 μL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat
• CD178 (Fas ligand, FasL) is a type-II-membrane protein, whose N-terminus is in the cytoplasm and its C-terminal region extends into the extracellular space
• Its receptor, FasR, is a cell-surface-type-I-membrane protein and a member of the tumor necrosis factor (TNF) and nerve growth factor (NGF) receptor family
• As a member of the TNF-cytokine family CD178 induces apoptosis when interacting with FasR
• CD178 may exist as either membrane bound (45 kD) or soluble forms (26 kD)
• The soluble protein can be released from cells upon cleavage by metalloproteinases
• Binding of CD178 to Fas leads to oligomerization of the receptor and triggers apoptotic cell death through the interaction of other proteins
• CD178 is predominantly expressed in activated T-lymphocytes and natural killer (NK) cells also it is expressed in the tissues of immune-privilege sites such as testis and eye
• CD178 expression is also reported in various tissues as thymus, liver, ovary, lung, heart and kidney
• It is assumed that induction of apoptosis through CD178 is predominantly involved in anti-viral immune responses
• CD178 is a cell surface molecule belonging to the tumor necrosis factor family, binds to its receptor Fas, thus inducing apoptosis
• Various cells express FAS, where CD178 is expressed predominantly on activated T cells
• FAS and CD178 are involved in the down-regulation of immune reactions as well as T cell-mediated cytotoxicity
• CD178 concentration has also been shown to be associated with atherosclerosis and inflammatory disease, in patients with hypertension
• The Fas/ CD178 system has been shown to play a role in a number of human diseases, for example AIDS, hepatitis or cancer.
