Sp1 was initially identified as a HeLa cell-derived factor that selectively activates in vitro transcription from the SV40 promoter and binds to the multiple GC boxes in the 21 bp repeated elements in SV40. The sequence specificity of DNA binding is conferred by Zn (II) fingers, whereas a different region of Sp1 appears to regulate the affinity of DNA binding. Sp1 belongs to a subgroup of transcription factors that are phosphorylated upon binding to promoter sequences.\u003c\/p\u003e \n\n\u003cp\u003eProduct: Rabbit IgG, 1mg\/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: p-Sp1 (T453) polyclonal antibody detects endogenous levels of Sp1 protein only when phosphorylated at Thr453\u003c\/p\u003e\n\n\u003cp\u003eNote: For research use only, not for use in diagnostic procedure.\u003c\/p\u003e\n\n\u003cp\u003eExtra Notes: Immunohistochemistry (IHC) analyzes of p-Sp1 (T453) pAb in paraffin-embedded human breast carcinoma tissue at 1:50.\u003c\/p\u003e \n\n\u003cp\u003eBioworld Molecular Weight: ~ 90 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
