CD95 (APO-1/Fas) Monoclonal Antibody (DX2), PerCP-eFluor™ 710, eBioscience™, Invitrogen™

Description

• Description: The DX2 monoclonal antibody reacts with human CD95 (Fas, Apo-1), a 40-50 kDa member of the TNFR superfamily
• CD95 is expressed by a broad range of hematopoietic and non-hematopoietic cells including monocytes, neutrophils, lymphocytes and fibroblasts
• Interaction of CD95 on mature lymphocytes with its ligand (FasL) induces apoptosis and is thought to be important in peripheral tolerance
• DX2 does not block binding of EOS9.1, another antibody specific for human CD95
• The DX2 monoclonal is reported to recognize dog/canine CD95
• Applications Reported: This DX2 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This DX2 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells
• This can be used at 5 μL (0.06 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
• PerCP-eFluor™ 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5
• We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative
• Please make sure that your instrument is capable of detecting this fluorochrome
• Fixation: Samples can be stored in IC Fixation Buffer (cat
• FAS (Fas, CD95, APO-1) is a 46 kDa transmembrane glycoprotein that functions as a cell death receptor of the TNFR (tumor necrosis factor receptor) superfamily
• FAS also exists in a soluble form that weight approximately 26kDa
• Stimulation of FAS results in aggregation of its intracellular FAS-associated death domains (FADD), formation of the death-inducing signaling complex (DISC) and activation of caspases
• The auto-proteolytic processing of the caspases in the complex trigger a downstream cascade that leads to apoptosis
• FAS has been shown to activate NF-kappaB, MAPK3/ERK1, MAPK8/JNK, and is involved in transducing the proliferating signals in normal diploid fibroblast and T cells
• At least eight alternatively spliced transcript variants encoding seven distinct isoforms have been described
• The isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full-length isoform
• The Fas/Fas ligand system has been shown to play a role in a number of human diseases such as AIDS, hepatitis and cancer
• It is also assumed that induction of apoptosis through FAS ligand pathway is predominantly involved in anti-viral immune responses.
