Form : |
Lyophilized from sterile 50 mM Tris, 100 mM NaCl, 20% glycerol, 0.05% Tween 20, pH 9.5. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. |
Molecular Mass : |
The recombinant human Beta-APP38/GST chimera consists of 277 amino acids and has a calculated molecular mass of 32.1 KDa. It migrates as an approximately 34 KDa band in SDS-PAGE under reducing conditions. |
Endotoxin : |
< 1.0 eu per μg of the protein as determined by the LAL method. |
Purity : |
>85 % as determined by SDS-PAGE |
Stability : |
Samples are stable for up to twelve months from date of receipt at -70oC. |
Storage : |
Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4℃ before opening to recover the entire contents. |
