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.
Alternative Name:
Heat shock factor 1, Heat shock factor protein 1, Heat shock transcription factor 1, HSF 1, hsf1, HSF1, HSTF 1, HSTF1,
Application Dilution: IHC: 1:50~1:200, IF: 1:50~1:200
Specificity: p-HSF1 (S303) polyclonal antibody detects endogenous levels of HSF1 protein only when phosphorylated at Ser303.
Immunogen:
Synthetic phosphopeptide derived from human HSF1 around the phosphorylation site of Serine 303.
MW: ~ 82 kDa
Swis Prot.: Q00613
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).
Format:
1 mg/ml in Phosphate buffered saline (PBS) with 0.05% sodium azide, approx. pH 7.2.
Storage:
Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles.
For research use only, not for use in diagnostic procedure.
