Phospho-HSF1 (Ser326) Antibody (MA5-32105) in IHC (P)

Immunohistochemistry analysis of paraffin-embedded Phospho-HSF1 (Ser326) in human tonsil tissue. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 20 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS. Incubation was done with monoclonal Phospho-HSF1 (Ser326) antibody (Product # MA5-32105) at a dil...

产品详细信息

Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.

靶标信息

All organisms respond to elevated temperatures and a variety of environmental stresses by rapid synthesis of heat shock RNAs and proteins. The regulation of heat shock gene transcription is mediated by the transcriptional activator, heat shock factor (HSF), which binds to heat shock response elements (HSEs). These HSEs are found as three repeats of a 5-nucleotide {nGAAn} module, arranged in alternating orientation and present upstream of all heat shock genes. The HSEs are highly conserved among species yet HSF purified from yeast, Drosophila and human have different molecular weights and the proteins do not show significant immunological cross reaction. Two HSFs have been identified in human cells, HSF1 and HSF2, which bind to the same HSEs and have 38% sequence identity. These factors are activated by distinct stimuli, HSF1 is responsive to classical stress signals such as heat, heavy metals and oxidative reagents, whereas HSF2 is activated during hemin-mediated differentiation of human erythroleukemia cells. HSF1 exists constitutively in the cytoplasm and the nucleus of unstressed cells as a monomer which lacks DNA binding activity. Through an unknown signal generated during stress, HSF1 becomes activated to a nuclear localized, trimeric state which binds to DNA. The phosphorylation of HSF1 is necessary for maximal transcription of heat shock genes.
