Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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
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.

Target Background

Involved in nervous system development and function. Involved in the positive regulation of voltage-gated sodium channel activity. Promotes neuronal excitability by elevating the voltage dependence of neuronal sodium channel SCN8A fast inactivation.
Gene References into Functions
  1. FGF12 has a potential role in ESCC. PMID: 29049013
  2. In this study, the authors observed that rs1460922 of FGF12 was significantly associated with VT and identified that a de novo variation of FGF12 may be an important genetic risk factor for the pathogenesis of VT. PMID: 28775062
  3. FGF12, RBFOX1, and MIR302F could be important in human heterotaxy, because they were noted in multiple cases. Further investigation into genes involved in the NODAL, BMP, and WNT body patterning pathways and into the dosage effects of FGF12, RBFOX1, and MIR302F is warranted. PMID: 27637763
  4. FGF12 strongly induced the quiescent and contractile vascular smooth muscle cell phenotype and directly promoted VSMC lineage differentiation. PMID: 27470512
  5. Results demonstrate that gain-of-function FHF mutations can cause neurologic disorder, and expand the repertoire of genetic causes (FHF1) and mechanisms (altered Nav gating) underlying early-onset epileptic encephalopathies and cerebellar atrophy PMID: 27164707
  6. Nine SNPs of the FGF12 gene were associated with Kashin-Beck disease. PMID: 26290467
  7. Data indicate that SCN5A variant (Nav1.5) p.H1849R affected interaction with fibroblast growth factor homologous factor (FHFs). PMID: 26392562
  8. Q7R-FGF12 is a disease-associated BrS mutation. Moreover, these data suggest for the first time that FHF effects on Na(+) and Ca(2+) channels are separable. PMID: 24096171
  9. VAX1 rs10787760, rs6585429 and rs1871345 polymorphisms may be involved in nonsyndromic cleft lip with or without cleft palate in Brazilian patients, but there is no association with polymorphisms in FGF12, VCL, or CX43 PMID: 23679094
  10. PHOX2B, FGF12 and GAD2 genes are hypermethylated in colorectal neoplastic tissue PMID: 22552777
  11. exogenous FGF12 can play a role in tissues by translocating into cells through the plasma membrane PMID: 21518765
  12. Fibroblast growth factor homologous factor 1B (FHF1B) modulated the cardiac sodium channel Nav1.5. PMID: 12401812
  13. x-ray crystal structure of FHF1b PMID: 12815063
  14. Data describe the biophysical characterization and folding of fibroblast growth factor homologous factor-1b (FHF-1b) in comparison with acidic fibroblast growth factor (FGF-1), and show that FHF-1 is significantly more stable than FGF-1. PMID: 18289114
  15. These findings suggest that FGF12 intracellularly suppresses radiation-induced apoptosis in mast cells independently of IB2. PMID: 18525161
