Regulatory Status Legend
The MFL4 monoclonal antibody, generated against mouse CD178 (Fas Ligand, CD95 Ligand), cross-reacts with the rat Fas Ligand antigen. MFL4 mAb detects rat Fas Ligand expressed by transfected cells, but not the parental cell line. In addition, the epitope detected by MFL4 can be induced on activated rat splenic T lymphocytes. The MFL4 mAb has been reported to inhibit killing of mouse lymphoma line A20.2J by rat FasL-transfected cells. The tissue distribution of mouse Fas Ligand has been well characterized. It is expressed at the mRNA and protein levels in a variety of tissues and cell types, including spleen, bone marrow, testis, uterus, eye, and activated lymphocytes. The expression of Fas Ligand in the rat has been detected in liver Kupffer cells, T cells in the central nervous system, spleen, and corpus luteum. MFL4 antibody reacts with the mouse Fas Ligand protein in a pattern similar to that of MFL3 antibody. Fas Ligand is a type-II transmembrane protein, a member of the TNF/NGF superfamily and a ligand for Fas (CD95). Fas Ligand and its counter-receptor CD95 are believed to participate in T-cell development, the regulation of immune responses, and cell-mediated cytotoxic mechanisms. It has been reported that human Fas Ligand is released from the surface of activated lymphocytes by metalloproteinase.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at http://www.bdbiosciences.com/documents/hamster_chart_11x17.pdf.
We have found that enriched splenic T cells are induced to express Fas Ligand by 6 - 8-hour culture with plate-bound anti-αβ TCR mAb R73 (Cat. No. 554910) and anti-rat CD28 mAb JJ316 (Cat. No. 554992). Because Fas Ligand is expressed at low density on activated cells, we recommend the use of a "bright" second-step antibody, such as Streptavidin-PE (Cat. No. 554061).
