< 1.0 EU per 1μg of the protein by the LAL method.
|
Formulation
|
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
|
Reconstitution
|
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
