|A DNA sequence encoding the human NAPA (NP_003818.2) (Met1-Arg295) was expressed with a polyhistidine tag at the N-terminus.|
|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.
|> 95 % as determined by SDS-PAGE.|
|Please contact us for more information.|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant human NAPA consists 310 amino acids and predicts a molecular mass of 35 kDa.|
|Lyophilized from sterile 50 mM Tris, 10 % Glycerol, pH 8.0.|
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|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.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
