We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Basically, we can dispatch the products out in 5-10 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Gene References into Functions
  1. this study shows FGFRL1 promotes ovarian cancer progression by crosstalk with Hedgehog signaling PMID: 29675438
  2. FGFRL1 is a transmembrane receptor that can induce the fusion of CHO cells to multinucleated syncytia. This cell fusion activity has been attributed to the extracellular Ig3 domain of the receptor. The Ig3 domain from humans, mice, chicken and fish stimulates fusion of CHO cells, while the Ig3 domain from lancelet and sea urchin does not. PMID: 28596102
  3. Both in vitro and in vivo studies determined that miR-210 promoted hepatocellular carcinoma (HCC), angiogenesis, and the corresponding mechanism was identified to be the direct targeting and inhibition of fibroblast growth factor receptor-like 1 (FGFRL1) expression PMID: 27666683
  4. FGFRL1 is a cell adhesion protein. PMID: 27220341
  5. functional evidence for a novel FGFRL1 poly-miRTS rs4647940 in a previously known 4p16.3 locus, and experimental and clinical genetics studies have shown both FGFRL1 and hsa-miR-140-5p are important for bone formation. PMID: 25941324
  6. Cell-cell fusion induced by the Ig3 domain of receptor FGFRL1 PMID: 26025674
  7. The signaling complex appears to integrate the input from FGFR and EphA4, and release the output signal through FRS2alpha. PMID: 20184660
  8. study identified a novel region of deletion mapping to 4p16.3 in 15 percent of bladder tumors and 24 percent of bladder cancer cell lines; FGFRL1, which maps within this region, was investigated as putative deletion target; average FGFRL1 protein expression was lower in bladder tumors compared to normal tissue, but downregulation was independent from 4p16.3 LOH status PMID: 23775577
  9. Interaction of FGFRL1 with Spred1 increases the proportion of the receptor at the plasma membrane. PMID: 21616146
  10. an important role for miR-210 as a tumor-suppressive microRNA with effects on cancer cell proliferation PMID: 21044961
  11. FGFRL1 is capable of inducing syncytium formation of heterologous cells in vitro. PMID: 20851884
  12. FGFRL1 is indeed a decoy receptor for FGFs. PMID: 19920134
  13. analysis of FGF18 and FGFR5(FGFRL1) expression in primary endothelial cells and vascular smooth muscle cells PMID: 16019430
  14. Screening of 241 different human tumors with the help of a cancer profiling array suggested major alterations in the relative expression of FGFRL1 in ovarian tumors PMID: 16273302
  15. The extracellular domain of recombinant FGFRL1 promoted cell adhesion, but not cell spreading. Adhesion was mediated by heparan sulfate glycosaminoglycans located at the cell surface. PMID: 18061161
  16. mutant FGFRL1 contributes to the skeletal malformations of the patient PMID: 19056490

Subcellular Location
Membrane; Single-pass type I membrane protein. Note=Predominantly localized in the plasma membrane but also detected in the Golgi and in secretory vesicles.
Tissue Specificity
Expressed preferentially in cartilaginous tissues and pancreas. Highly expressed in the liver, kidney, heart, brain and skeletal muscle. Weakly expressed in the lung, small intestine and spleen.
