General description
Sp1 is a human transcription factor involved in gene expression in the early development of an organism. The protein is 785 amino acids long, with a molecular weight of 95 kDA. The SP1 transcription factor contains a zinc finger protein motif, by which it binds directly to DNA and enhances gene transcription. Sp1 has always been described as a ubiquitous transcription factor that is required for the constitutive and inducible expression of a variety of genes, such as in cell cycle or mammalian development.
Specificity
Expected to cross-react with rat.
Recognizes Sp1, Mr 105 kDa and 95 kDa.
Immunogen
Full length human Sp1 protein.
Application
Immunoprecipitation:
4 µg of this lot immunoprecipitated Sp1 from 500 µg of HeLa nuclear extract.
NOTE: A previous lot successfully immunoprecipitated the α-1 subunit using the Catch and Release v2.0 Reversible Immunoprecipitation System (Catalog # 17-500). See manual for more information and protocol: www.millipore.com
Chromatin Immunoprecipitation:
Reported by an independent laboratory.
Immunofluorescence:
Reported by an independent laboratory.
Electrophoretic Mobility Shift Assay (EMSA):
1 µL of a previous lot of this antibody has been reported by an independent laboratory to supershift DNA complexes containing recombinant Sp1 and endogenous Sp1 from HeLa cells in EMSA.
