Description

Fibroblast growth factor receptor 2 (FGFR2) serves as a critical membrane-bound tyrosine kinase that orchestrates cellular responses to FGF ligands, influencing proliferation, differentiation, and survival across multiple tissue types. This receptor plays particularly important roles in developmental processes, neural function, and tissue homeostasis, while its dysregulation has been implicated in various malignancies, making it a significant target for researchers investigating cancer biology, cardiovascular development, and stem cell differentiation.

This recombinant monoclonal antibody, clone 2E9, offers the reproducibility and consistency that demanding experimental workflows require. Because it is generated from a defined sequence rather than traditional hybridoma methods, researchers can expect reliable lot-to-lot performance, eliminating a common source of experimental variability when working with this important signaling receptor.

Western blot validation demonstrates robust detection across multiple species and tissue types, with confirmed performance in rat brain and lung lysates as well as mouse brain lysates at dilutions ranging from 1:500 to 1:5000. The observed band at approximately 145 kDa runs higher than the predicted molecular weights, which is consistent with the extensive post-translational modifications characteristic of FGFR2, including N-linked glycosylation that is well-documented for this receptor family. This cross-species reactivity across human, mouse, and rat samples provides flexibility for researchers working with different model systems or translational studies.

Whether investigating FGFR2 signaling in neurodevelopmental contexts, exploring its role in tumor progression, or examining receptor dynamics in stem cell populations, this antibody delivers the specificity and versatility needed for meaningful experimental insights.

Target Background

Function(From Uniprot)

Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation, migration and apoptosis, and in the regulation of embryonic development. Required for normal embryonic patterning, trophoblast function, limb bud development, lung morphogenesis, osteogenesis and skin development. Plays an essential role in the regulation of osteoblast differentiation, proliferation and apoptosis, and is required for normal skeleton development. Promotes cell proliferation in keratinocytes and immature osteoblasts, but promotes apoptosis in differentiated osteoblasts. Phosphorylates PLCG1, FRS2 and PAK4. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. FGFR2 signaling is down-regulated by ubiquitination, internalization and degradation. Mutations that lead to constitutive kinase activation or impair normal FGFR2 maturation, internalization and degradation lead to aberrant signaling. Over-expressed FGFR2 promotes activation of STAT1.
