Pro42-Gly403 |
| Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
| Purity : |
> 97 % as determined by SDS-PAGE |
| Storage : |
Samples are stable for up to twelve months from date of receipt at-70 centigrade. Store it under sterile conditions at-20 centigrade to-80 centigrade. 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 of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents. |
