HSF1, or heat shock factor 1, belongs to a family of Heat Shock transcription factors that activate the transcription of genes encoding products required for protein folding, processing, targeting, degradation, and function (2). The up-regulation of HSP (heat shock proteins) expression by stressors is achieved at the level of transcription through a heat shock element (HSE) and a transcription factor (HSF) (3, 4, 5). Most HSFs have highly conserved amino acid sequences. On all HSFs there is a DNA binding domain at the N-terminus. Hydrophobic repeats located adjacent to this binding domain are essential for the formation of active trimers. Towards the C-terminal region another short hydrophobic repeat exists, and is thought to be necessary for suppression of trimerization (6). There are two main heat shock factors, 1 and 2. Mouse HSF1 exists as two isoforms, however in higher eukaryotes HSF1 is found in a diffuse cytoplasmic and nuclear distribution in un-stressed cells. Once exposed to a multitude of stressors, it localizes to discrete nuclear granules within seconds. As it recovers from stress, HSF1 dissipates from these granules to a diffuse nuceloplasmic distribution. HSF2 on the other hand is similar to mouse HSF1, as it exists as two isoforms, the alpha form being more transcriptionally active than the smaller beta form (7, 8). Various experiments have suggested that HFS2 may have roles in differentiation and development (9, 10, 11).

Monoclonals of this antigen are available in different clones. Each murine monoclonal anibody has his own affinity specific for the clone. Mouse monoclonal antibodies are purified protein A or G and can be conjugated to FITC for flow cytometry or FACS and can be of different isotypes.Rats are used to make rat monoclonal anti mouse antibodies. There are less rat- than mouse clones however. Rats genes from rodents of the genus Rattus norvegicus are often studied in vivo as a model of human genes in Sprague-Dawley or Wistar rats.
Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
