Catalog No. ABIN967452

Product Details anti-SPI1 Antibody

Target: SPI1 (Spleen Focus Forming Virus (SFFV) Proviral Integration Oncogene Spi1 (SPI1))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This SPI1 antibody is un-conjugated

Application: Western Blotting (WB), Immunoprecipitation (IP)

Brand: BD Pharmingen™

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us 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.

Purification: The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Immunogen: PU.1 Fusion Protein

Clone: G148-74

Isotype: IgG2a

Application Details

Application Notes: Applications include gel shift, western blot analysis (1-2 µg/ml) and immunoprecipitation. The antibody has been shown to recognize in vitro translated PU.1 and PU.1 expressed as a recombinant protein in bacteria. In. In gel shift assays using µB as a probe (µB is a transcriptional element in the immunoglobulin heavy chain enhancer), G148-74 supershifts the complex of probe and PU.1.

Background: PU.1 is an ets-related transcription factor expressed in B lymphocytes and macrophages. It was initially identified as the oncogene Spi-1 which was found to block erythroblast differentiation. PU.1 functions by binding transcriptional control elements such as µB in the immunoglobulin heavy chain enhancer and pi adjacent to µE2. It has been shown to form a complex with NF-EM5, a B cell transcription factor, resulting in the activation of the immunoglobulin kappa 3' enhancer. PU.1 also appears to be critically involved in the control of monocyte development by regulating the expression of the macrophage colony-stimulating factor receptor. PU.1 runs as a 40-42 kDa protein on SDS-PAGE. G148-74 recognizes human PU.1, an Ets-related transcription factor. PU.1 is expressed in B lymphocytes and macrophages and like other Ets-related proteins, binds to consensus sites in DNA through an 85 amino acid Ets domain in the carboxyl terminal region of the protein. The antibody was raised against a bacterially expressed GST-PU.1 fusion protein.
