Anti-HSF1 Antibody


Anti-HSF1 Antibody

Product type:  Primary Antibody
Clonality:         Polyclonal
Source:            Rabbit
Immunogen:   Recombinant Full length human HSF1 expressed in E. coli.
Other name:   Heat shock factor 1
Description:    DNA-binding protein that specifically binds heat shock promoter elements (HSE) and activates transcription. In higher eukaryotes, HSF is unable to bind to the HSE unless the cells are heat shocked. 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.
Purification: Purified by affinity chromatography using protein A/G affinity matrix.
Specificity: This antibody detects HSF1 protein in human and mouse cell extracts.

Western Blotting      1:2,000 to 5,000
ELISA                      1:1,000
