纯度> 95 % as determined by SDS-PAGE.内毒素< 1.0 EU per μg protein as determined by the LAL method.生物活性Immobilized Human EphA1 His (Cat: 15789-H08H) at 2 μg/ml (100 μl/well) can bind Human Ephrin-A1 Fch (Cat: 10882-H03H), the EC50 of Human Ephrin-A1 Fch is 25-90 ng/mL.蛋白构建A DNA sequence encoding the human EPHA1 (EAL23789.1) (Met1-Glu547) was expressed with a polyhistidine tag at the C-terminus.Accession#EAL23789.1表达宿主HEK293 Cells种属Human预测 N 端Lys 26分子量The recombinant human EPHA1 consists 533 amino acids and predicts a molecular mass of 58 kDa.缓冲液Lyophilized from sterile PBS, pH 7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.运输方式In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.稳定性 & 储存条件Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
