Thermo Scientific™ CellSensor™ irf1-bla HEL Cell Line
Description
Jak/Stat signaling pathways play essential roles in the cellular responses to distinct cytokines. One of Jak/Stat pathways, Jak2/Stat5, mediates cell proliferation in response to Interleukin-3 (IL-3), prolactin, erythropoietin (Epo), and granulocyte-macrophage colony stimulating factor (GM-CSF). JAK2 gene knock-out causes embryonic lethality due to defective erythropoiesis, suggesting the Jak2/Stat5 pathway plays important role in red blood cell formation. Recent discovery of activating mutation in JAK2 (V617F) present in high percentage of myeloproliferative disease (MPD) patients suggests Jak2/Stat5 pathway to be the potential therapeutic target for certain forms of MPD. The activated transcription factor Stat5 dimers recognize and bind to a specific palindromic DNA sequence found in the promoter region of β-casein, interferon regulatory factor-1 (irf-1) and a number of other genes.
The CellSensor™ irf1-bla HEL cell line contains a beta-lactamase reporter gene under control of the interferon regulatory factor-1 (irf1) response element stably integrated into HEL cells. HEL cells are a human erythroleukemia cell line that is growth factor independent and contains a endogenous homozygous JAK2V617F mutation. This cell line validated for IC50 and Z'-Factor under optimized conditions using Jak Inhibitor 1 (Figure 1). This cell line has also been tested under variable experimental conditions, including DMSO concentration, cell number, stimulation time, and substrate loading time. Academic and non-profit customers, please inquire for special pricing.
