Interpolated concentrations of native FGF-21 in human serum and plasma samples.
The concentrations of FGF-21 were measured in duplicates, interpolated from the FGF-21 standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 100%, plasma (citrate) 100%, plasma (EDTA) 100%, and plasma (heparin) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean FGF-21 concentration was determined to be 657 pg/mL in neat serum, 772 pg/mL in neat plasma (citrate), 289 pg/mL in neat plasma (EDTA), and 711 pg/mL in neat plasma (heparin).

Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native human FGF-21 was measured in serum and plasma samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS for serum and plasma samples.
Recombinant human FGF-21 was spiked into EDTA plasma samples and diluted in a 2-fold dilution series in Sample Diluent NS.

Product details
Human FGF21 ELISA Kit ab222506 is a rapid single-wash 90-min Sandwich ELISA to measure Human FGF21 in citrate plasma, EDTA plasma, heparin plasma, milk, serum. This SimpleStep sensitivity is 3.3 pg/mL.
How the assay works
Human FGF21 SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

FGF-21, or Fibroblast growth factor 21, is a member of the fibroblast growth factor family encoded by the gene FGF21. FGF-21 helps regulate glucose homeostasis by mediating liver signaling to the brain by inducing phosphorylation of the mitogen-activated protein kinase extracellular signal-related kinase 1. FGF-21 is principally expressed in the liver in response to fasting, where it mediates several metabolic responses such as ketogenesis, hepatic fatty acid oxidation, and resistance to growth hormones. In addition, it is involved with embryonic development, cell growth, morphogenesis, and tissue repair. Serum levels of FGF-21 have been found to be elevated in patients with type 2 diabetes mellitus, and higher levels of FGF-21 also correlate with higher liver fat content.

Biological function summary
FGF21 influences glucose and lipid metabolism. It does not act as part of a larger protein complex. Instead it directly affects metabolic processes enhancing insulin sensitivity and lipid oxidation while reducing body weight. These actions help maintain energy balance and homeostasis making FGF21 an important player in metabolic control.
Pathways
FGF21 plays a significant role in the insulin signaling pathway and PPARγ coactivator 1α (PGC-1α) pathway. These pathways regulate cellular energy metabolism and mitochondrial biogenesis respectively. FGF21 interacts with other molecules such as PPARα (peroxisome proliferator-activated receptor alpha) to exert its effects demonstrating its integration into broader metabolic networks. FGF21's interaction with these pathways highlights its function in energy utilization and storage.
