Product Name :HSF1 (phospho-S303) polyclonal antibody
Reactivity :Human,Mouse,Rat
Application_all :IHC: 1:50~1:200
IF: 1:50~1:200
Background :Heat shock transcription factors (HSF, also designated HSTF) 1 and 2 are involved in this regulation. 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.
Product :Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2
Purification&Purity :The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
Storage&Stability :Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.
Specificity :p-HSF1 (S303) polyclonal antibody detects endogenous levels of HSF1 protein only when phosphorylated at Ser303.
Note :For research use only, not for use in diagnostic procedure.
Alternative Name :Heat shock factor 1; Heat shock factor protein 1; Heat shock transcription factor 1; HSF 1; hsf1; HSF1; HSTF 1; HSTF1;
Immunogen :Synthetic phosphopeptide derived from human HSF1 around the phosphorylation site of Serine 303.
Modification :Phosphorylation
