Add to my product list
iLite? FGF21 Assay Ready Cells are based on the human embryonic kidney cell line, HEK293 (ATCC# CRL-1573), and have been genetically engineered and optimized to be responsive to human FGF21 and analogues of human FGF21 by specific and proportional expression of Firefly Luciferase.
Normalization of cell counts and serum matrix effects is obtained by a second reporter gene, a Renilla Luciferase reporter gene construct, under the control of a constitutive promotor.

- Application
- Background
- Content
The iLite? FGF21 Assay Ready Cells can be used in an assay for the quantification of the potency of analogues of human FGF21, the potency of FGFR1c antagonists or a neutralizing antibody response against such products in human serum in the absence of serum matrix effects.
Application Notes for the following assays are available:
-
Quantification of FGF21 using iLite? FGF21 Assay Ready Cells (E--259--GB)
-
Determination of neutralizing antibodies against FGF21 using iLite? FGF21 Assay Ready Cells (E--258--GB)
Human fibroblast growth factor 21 (FGF21) is a member of a family of the atypical fibroblast growth factors that include FGF19 and FGF23 in man. FGF21 lacks the heparin-binding domain of conventional FGFs and can consequently diffuse throughout the body and function as a hormone. FGF21 stimulates glucose uptake in adipocytes and the effects on glucose uptake is additive with insulin (1).
The iLite? FGF21 Assay Ready Cells are a genetically engineered reporter gene cell line responsive to FGF21 by specific and proportional expression of Firefly Luciferase. The receptor chain FGFR1c is overexpressed on the surface together with the co-factor β-Klotho which has been genetically optimized to enhance sensitivity. Normalization of cell counts and serum matrix effects is obtained by a second reporter gene, a Renilla Luciferase reporter gene construct, under the control of a constitutive promotor.
