Information d'application

Protocole: 1. Maintain cells in culture with 10% FBS medium, change the medium one day before starting the induction of apoptosis. Harvest and pellet the cells, resuspend in 10% FBS medium at a density of 0.5-1.0 x 10^6 cells/ml.
2. In a 96-well microtiter plate, add 2.5 µg/50 µl CD95 NA/LE™, 0.5 µg/50 µl rProt G, 0.5-1.0 x 10^5 cells and 10% FBS medium to a total volume of 200 µl. Negative controls should consist of: 1) 0.5-1.0 x 10^5 cells with 10% FBS medium alone (200 µl total volume), and 2) 0.5-1.0 x 10^5 cells with 0.5 µg/50 µl rProtG and 10% FBS medium.
3. Incubate the 96-well plate at 37°C, 5% CO2, for 12-24 hours. Traditionally, apoptosis has been observed by light microscopy, MTT, or gel electrophoresis (DNA fragmentation). Investigators may be interested in several products offered by BD Biosciences that may be used for the detection of apoptotic cells by flow cytometry: ApoDirect™ Kit (Cat. No. 556381), ApoBRDU™ Kit (Cat. No. 556405) and Annexin V-FITC (Cat. No. 556420, Cat. No. 556419). Because these methods vary in sensitivity, it may be necessary to titer the rProtG and/or CD95 NA/LE™ to obtain optimal results.
Notes: The suggestions given in this procedure are based on conditions that were found to be optimal for the induction of apoptosis by anti-human CD95 (Fas). Studies have shown that the addition of protein G can significantly enhance the efficiency of DX2 in this type of functional assay. It is important to note that there is a great deal of variation between cell lines in the level of apoptosis that can be induced through the Fas receptor. It has been reported that, although some cells express the Fas antigen, they do not necessarily undergo Fas-mediated apoptosis (i.e., the Fas antigen expressed may be anti-Fas sensitive or insensitive). Daudi, Jurkat, and HPB-ALL cells are good positive controls as they are strongly induced by anti-Fas to undergo apoptosis.

Sujet: Reacts with the 45 kDa transmembrane cell surface Fas or Apo-1 antigen (designated CD95 at the Fifth HLDA Workshop) which is expressed on a variety of normal and neoplastic cells. The Fas/Apo-1 antigen is a polypeptide, which plays a role in the programmed sequence of events leading to cell death, termed apoptosis. The DX2 clone specifically reacts with murine L cells, murine L1210 leukemia cells and murine P815 mastocytoma cells transfected with human Fas cDNA but not with untransfected parental cell lines. Cross-linking with DX2 delivers an apoptotic signal indicating that DX2 recognizes a functional epitope of the CD95 antigen.
Synonyms: Fas/APO-1
