Bioactivity Determination of Native and Variant Forms of Therapeutic Interferons
Figure 2
Intra-assay variation. Three samples were used. Sample 1 was the In-House reference standard (a), with sample #2 and #3 being final products reconstituted from final drug products in syringes (b, c). Each dose was run in triplicate and tested on 5 different plates. The graphs depict the linear range of the tested doses as determined by comparison to the NIH IFN-β standard.
