Bioactivity, ELISA, Immunogen, SDS-PAGE, WB
Stability
Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for one week. Store at -20 to -80°C for twelve months from the date of receipt.
Endotoxin
<0.1 EU/μg of the protein by the LAL method.
Purity
>90% as determined by SDS-PAGE.
Bioactivity
Interferon was titrated with the use of the cytopathic effect inhibition assay. In this antiviral assay forinterferon, about 1 unit/ml of interferon is the quantity necessary to produce a cytopathic effect of 50%. As there is no international Rat IFN-beta standard, units are determined with respect to the international reference standard for mouse interferon alpha/beta (mouse IFN-alpha/beta) provided by the National Institutes of Health.
