HSF1 and HSF2 are upregulated by estrogen at both the mRNA and protein level. HSF1 is normally found as a monomer whose transcriptional activity is repressed by constitutive phosphorylation. Upon activation, HSF1 forms trimers, gains DNA binding activity and is translocated to the nucleus. HSF2 activity is associated with differentiation and development, and, like HSF1, binds DNA as a trimer. Both HSF1 and HSF2 are known to be induced by proteasome inhibitors of the ubiquitin pathway.\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-HSF1 (S303) polyclonal antibody detects endogenous levels of HSF1 protein only when phosphorylated at Ser303.\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-HSF1 (S303) pAb in paraffin-embedded human breast carcinoma tissue at 1:50.showing cytoplasmic and nucleus staining.
