Notes
The Antibody Pair can be used to quantify Human FGF21. BSA and Azide free antibody pairs include unconjugated capture and detector antibodies suitable for sandwich ELISAs. The antibodies are provided at an approximate concentration of 1 mg/ml as measured by the protein A280 method. The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Both capture and detector antibodies are rabbit monoclonal antibodies delivering consistent, specific, and sensitive results.
For additional information on the performance of the antibody pair, see the equivalent SimpleStep ELISA® Kit (Human FGF21 ELISA Kit ab222506), which uses the same antibodies. However, due to differences in their formulation, this antibody pair cannot be used with the consumables provided with our SimpleStep ELISA Kits. Please note that the range provided for the pairs is only an estimation based on the performance of the related product using the same antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody pair in your assay.
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
The pair can be used in variety of assays and platforms including but not limited to:
- Sandwich ELISA
- FRET/TR-FRET/HTRF
- Meso Scale Discovery® (MSD®)
- Bead-based assays
- AlphaLISA®/AlphaScreen®
- DELFIA® immunoassays
- Simoa® and Single Molecule Counting (SMC™) immunoassays
- Multiplex
Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:
- Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
- Concentration of ~1 mg/ml as measured by the protein A280 method.
We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.
Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.
Please note:
The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.
The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.
We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

- Activity summary
FGF21 or fibroblast growth factor 21 is an important metabolic regulator. It is a member of the fibroblast growth factor family but unlike many others FGF21 functions mainly in endocrine signaling. The molecular weight of FGF21 is approximately 22 kDa. This protein is expressed in tissues such as the liver adipose tissue and pancreas. Because of its endocrine roles FGF21 travels through the bloodstream to exert its functions on distant organs.
- 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.
- Associated diseases and disorders
FGF21 has connections to conditions such as obesity and type 2 diabetes. Its role in improving insulin sensitivity and promoting lipid oxidation makes it a molecule of interest in combating metabolic syndrome. FGF21 also has a relationship with hepatic proteins such as insulin receptor substrates (IRS) which play roles in liver functioning. Understanding these relationships offers insights into potential therapeutic strategies targeting metabolic disorders.
