HSF1 Antibody (10H8) is a rat monoclonal IgG1 antibody that detects HSF1 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry (IHC). HSF1 (10H8) monoclonal antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase, phycoerythrin, fluorescein isothiocyanate, and multiple Alexa Fluor® conjugates. HSF1, or heat shock factor 1, plays a crucial role in the cellular response to stress by regulating the expression of heat shock proteins, which are essential for protein folding and protection against cellular damage. HSF1 is primarily located in the cytoplasm under normal conditions, where HSF1 exists as a monomer; however, upon stress, HSF1 undergoes a conformational change, allowing trimerization and translocation to the nucleus. This translocation enables HSF1 to bind to heat shock elements in the promoter regions of target genes, thereby initiating the transcription of heat shock proteins that help maintain cellular homeostasis during stressful conditions. HSF1 regulation is influenced by post-translational modifications, such as phosphorylation, which can either activate or repress transcriptional activity, highlighting the importance of precise control over HSF1 function in cellular stress responses.

To whom it may concern, I have used this antibody in previous experiments and would just like to know if you can provide any information as to what each of the three bands revealed through Western Blot correspond to in reference to the HSF1 protein?

Asked by: rejimenez3
Thank you for your question. Unfortunately, we have not further characterized the identity of separate bands of similar molecular weight that we observed when testing this antibody in different cell lines. Representative Western blot data is shown on our website for this HSF1 antibody. According to Uniprot, there are 2 isoforms described with predicted molecular weights of ~ 57 and 53 kDa, however due to post-translational modifications the observed molecular weight for HSF1 protein is higher and typically greater than 90 kDa.

When should the TransCruz reagent sc-13516 X be used instead of the standard form sc-13516?

Asked by: jerojero
Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
