Anti-Growth Factor Independence-1 antibody, Mouse monoclonal，200UL，G6670-200UL，Sigma

General description

Monoclonal Anti-Growth Factor Independence-1 (GFI1) (mouse IgG1 isotype) is derived from the hybridoma 2.5D.17 produced by the fusion of mouse myeloma cells (SP2 cells) and splenocytes from BALB/c mice immunized with rat GFI1. Growth Factor Independence 1 (GFI1) is a zinc-finger transcriptional repressor, that is located on human chromosome 1p22. Gfi1 is highly expressed in thymus while Gfi1B is the predominant factor expressed in spleen, and both are expressed in bone marrow. It has a repression domain named SNAG at the N-terminal.† The protein also has a zinc finger DNA binding domain that is homologous to the domain in Gfi1B. Both bind to same consensus DNA sequence

Immunogen

rat growth factor independence-1 (GFI1).

Application

Monoclonal Anti-Growth Factor Independence-1 (GFI1) antibody may be used in:

• immunoblotting
• immunohistochemistry
• EMSA (electrophoretic mobility shift analysis)

Biochem/physiol Actions

Growth factor independence-1 (Gfi1) plays a key role in hematopoiesis along with Gfi1B proteins. Cytokines that regulate innate immunity induce Gfi1 expression. Deficiency of this protein causes thymic and peripherial T lymphopenia and severe abnormalities in pre-T-cell development in mice. Mutations in this gene cause defects in T lymphocyte function and development in humans. Gfi1 autoregulates its expression in T lymphocytes.
The antibody epitope resides within the GFI1 SNAG transcriptional-repression domain (amino acids 7-26).

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Analysis Note

The antibody may also be used in EMSA (electrophoretic mobility shift analysis).
