Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

Applications include western blot analysis (0.5-2 µg/ml). Additional applications not routinely tested at BD Biosciences Pharmingen include gel shift and immunoprecipitation. Clone G146-254 has been shown to recognize in vitro translated, recombinant bacterially expressed, and endogenous B cell Fli-1. In gel shift assays this antibody supershifts complexes of Fli-1 and DNA probe.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. 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.

Fli-1 is a 50 kDa ets-related transcription factor.  Like other ets-related proteins it binds to consensus sites in DNA through a 85 amino acid ets domain in the carboxyl region of the protein.  Fli-1 is associated with Ewing sarcoma through at (11;22)(q24;q12) chromosomal translocation. This translocation brings the 5' region of the EWS gene into conjunction with the 3' region of the Fli-1 gene encoding the ets-DNA binding domain. Such a translocation is found in 85% of Ewing sarcomas. The resulting fusion protein has the DNA binding activity of Fli-1 and, with the EWS domain, it is also a more potent transcriptional activator than Fli-1 itself.  The strong transforming activity of the EWS-Fli-1 fusion protein may in part be due to its ability to trans-activate the promoter for c-myc. C-myc is known to be elevated in Ewing sarcomas.  Clone G146-254 was raised against a bacterially expressed Fli-1 ets domain fusion protein.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
