Human GFR alpha 1 Protein
Recombinant Human GFR alpha 1 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp25-Ser424.[Accession | NP_665736.1]
The protein has a predicted MW of 45.8 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human GFR alpha 1 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
The purity of Human GFR alpha 1 is greater than 95% as determined by SEC-HPLC.
Immobilized Human GDNF, No Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human GFR alpha 1, His Tag with the EC50 of 5.0ng/ml determined by ELISA.
Neuroblastomas often undergo spontaneous differentiation and/or regression in vivo, which is at least partly regulated by the signals through neurotrophins and their receptors. Recently, glial cell line-derived neurotrophic factor (GDNF) and a second family member, neurturin (NTN), have been found to mediate their signals by binding to a heterotetrameric complex of c-Ret tyrosine kinase receptors and glycosylphosphatidylinositol-linked proteins, GFR alpha-1 (GDNFR-alpha) or GFR alpha-2 (TrnR2/GDNFR-beta/NTNR-alpha/RETL2).
