Patented technology
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Conjugation ready
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

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.

Sandwich ELISA
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. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended 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 in your assay.

Supplementary information

FGF19 also known as fibroblast growth factor 19 is a 251 amino acid protein with a molecular mass of approximately 27 kDa. It is mostly expressed in the liver small intestine and to some extent in the gallbladder. FGF19 is related to the FGF family of growth factors which are involved in a variety of developmental and physiological processes. Unlike many other FGF members FGF19 lacks a heparin-binding domain which influences its receptor binding characteristics. Researchers frequently use FGF19 ELISA kits and FGF19 assays to study this protein due to its significance in regulating bile acid metabolism.
Biological function summary

Fibroblast growth factor 19 participates in maintaining metabolic homeostasis and controlling bile acid synthesis. It acts by binding to a receptor complex composed of FGFR4 and beta-Klotho which signals the regulation of energy balance and interaction with other metabolic targets. FGF19 protein triggers pathways that modulate glucose and lipid metabolism making it an important factor in metabolic health. Its regulation of lipid and glucose processes emphasizes its role in metabolic control systems and potential impacts on obesity and diabetes management.

Pathways

The fibroblast growth factor 19 engages in two critical signaling routes: the MAPK/ERK and the PI3K/AKT pathways. These pathways are fundamental in cell proliferation differentiation and survival. FGF19 through FGFR4 activation influences regulatory proteins and factors downstream bridging interactions with other key molecules such as insulin and leptin pathways. This regulatory mechanism contributes to its ability to fine-tune a wide range of metabolic functions and influences energy balance.

Fibroblast growth factor 19 shows a significant connection to non-alcoholic fatty liver disease (NAFLD) and certain forms of cancer. Altered expression levels of FGF19 associate with liver conditions due to its role in bile acid regulation and energy homeostasis. In cancer particularly hepatocellular carcinoma the dysregulation of FGF19 and its receptor plays a part in unchecked cellular proliferation and tumorigenesis. Researchers have noted connections with proteins such as FGFR4 and beta-Klotho highlighting their collaborative roles in disease progression and potential therapeutic targeting strategies.
