Name : Human RGMa Protein
Product Source :
Recombinant Human RGMa Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Cys48-Gly422.[Accession | Q96B86-1]
Molecular Weight :
The protein has a predicted MW of 44.5 kDa. Due to glycosylation, the protein migrates to 45-48 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-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.
Product Concentration :
Tris-Bis PAGE Human RGMa on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human RGMa is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human RGMa, His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Human Neogenin, hFc Tag with the EC50 of 0.17μg/ml determined by ELISA.
Background :
Repulsive guidance molecule (RGM) is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that has diverse functions in the developing and pathological central nervous system (CNS). The binding of RGM to its receptor neogenin regulates axon guidance, neuronal differentiation, and survival during the development of the CNS. RGMa induces T cell activation in experimental autoimmune encephalomyelitis (EAE), which is the animal model of multiple sclerosis (MS). RGM is expressed in pathogenic Th17 cells and induces neurodegeneration by binding to neogenin.
Synonyms :
RGMA; RGM
