The PathHunter PRLR-JAK1 Functional assay cell line is a stable, engineered cell line for use in studying drug candidates (small molecules or biologics) targeting CTKs. This cell line enables assessment of PRLR activation via detection of JAK1 mediated phosphorylation-induced SH2 domain protein recruitment. This product uses EFC technology. The included cell line overexpresses ProLink-tagged PRLR cytokine receptor, an untagged CTK JAK1 and EA-tagged SH2 domain protein. Upon activation of the cytokine receptor, CTK-based receptor phosphorylation leads to SH2-EA recruitment and production of EFC signal. This stable modified cell line is provided as two vials of cryopreserved cells. For detailed product information, User Manual and datasheet, visit www.discoverx.com/kinases.
