Recombinant Human FGFR2 alpha

Recombinant Human FGFR2 alpha (IIIc) (C-Fc) (C14C)

产品说明(Description)

Recombinant Human Fibroblast growth factor receptor 2 (IIIc) is produced by our Mammalian expression system and the target gene encoding Arg152-Glu377 is expressed with a Fc tag at the C-terminus.

Accession #: P21802

Known as: FGF R2a; FGFR2 alpha

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control)

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 

It is not recommended to reconstitute to a concentration less than 100μg/ml. 

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.  

Aliquots of reconstituted samples are stable at < -20°C for 3 months.

 

背景(Background)

FGFR2, also known as CD332, belongs to the fibroblast growth factor receptor subfamily where amino acid sequence is highly conserved between members and throughout evolution. FGFR2 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. Four distinct genes encoding closely related FGF receptors, FGF R1 - 4, are known. A frequent splicing event involving FGF R1 and 2 results in receptors containing all three Ig domains, referred to as the alpha  isoform, or only IgII and IgIII, referred to as the beta  isoform. Only the alpha  isoform has been identified for FGF R3 and FGF R4. 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.
