稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
Fibroblast Growth Factor Receptor 4 (FGFR4) is a member of the fibroblast growth factor receptor family, which plays a crucial role in various biological processes, including cell growth, differentiation, and metabolism. FGFR4 is particularly associated with the progression of several types of cancers, such as hepatocellular carcinoma and prostate cancer, where its overexpression correlates with poor prognosis. Given its significant role in tumorigenesis, FGFR4 has emerged as a potential therapeutic target, driving research into the development of FGFR4-specific inhibitors and therapies. The study of FGFR4 recombinant proteins is vital for understanding its structure-function relationships and interactions with ligands, which can inform the design of selective inhibitors. Furthermore, recombinant FGFR4 proteins facilitate the investigation of downstream signaling pathways, such as the MAPK and PI3K/Akt pathways, that are activated upon FGFR4 engagement. Advances in biotechnological methods have enabled the production of these proteins in various systems, allowing researchers to conduct detailed functional assays and structural analyses. Overall, the characterization of FGFR4 recombinant proteins is a foundational step in developing targeted therapeutics aimed at treating FGFR4-driven malignancies and improving clinical outcomes for patients.
