Source :	HEK293
Species :	Human
Tag :	C-His
Protein length :	Leu26-Gly171
Form :	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Bio-activity :	Human EphA7, His Tag immobilized on CM5 Chip can bind Human Ephrin-A4, His Tag with an affinity constant of 0.113 μM as determined in SPR assay (Biacore T200).
Molecular Mass :	The protein has a predicted MW of 17.5 kDa. Due to glycosylation, the protein migrates to 18-25 kDa based on Tris-Bis PAGE result.
Endotoxin :	Less than 1EU per μg by the LAL method.
Purity :	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Storage :	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
Reconstitution :	Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
