Rabbit polyclonal antibody to HSF1 (phospho-Ser303)
Specificity
The antibody detects endogenous level of HSF1 only when phosphorylated at serine 303.
Applications
WB, IHC
Dilutions
Western blotting: 1:500~1:1000 Immunohistochemistry: 1:50~1:100
Reactivity
Human
Immunogen
Peptide sequence around phosphorylation site of serine 303 (P-P-S(p)-P-P) derived from Human HSF1.
Host
Rabbit
Clonality
Polyclonal
Conjugate
Unconjugated
Purification
Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
