For parallelism and recovery assessments, plasma samples were spiked with 86.6 and 259.8 ng/L (25 or 75 pmol/L) BNP and measured in the BNP RIA as well as the total-BNP and BNP1-32 Luminex assays. Samples were also serially diluted to assess parallelism.
"These assays are simple to use and generate accurate, robust and reproducible results, which can accelerate the process of demonstrating biosimilarity, and the development of lot release assays for drug candidates," said Fiona Greer, global director, Biopharma Services Development at SGS.

However, this is not the case for bioassays and ELISAs, as there are many other factors required for an assay to work correctly, and any one can go awry.
These provided correlation and mean difference values for both assays. Both procedures utilised Microsoft Excel and Analyse-it software (10).
All three assays require very little specimen preparation and the procedures are simple to follow.
These 19 papers describe and evaluate a range of assay methods and associated topics, including endothelial cell biology, proliferation and migration assays, assays of tubule formation, models of the effects of the hemodynamic environment, whole or partial vessel outgrowth assays, endothelial-mural cell interactions, membrane and intracellular signaling events, implantation of sponges and polymers, assays in the chick, corneal assays, dorsal air sac models, chamber assays, tumor models, imagable models and vascular imaging, biological and clinical impact of the use of stem cells, a novel trial design of novel monitoring methods and future directions.
Although real-time PCR or pyrosequencing is more rapid than high-throughput assays for mutation detection (4,5), the conventional PCR technique can be applied to detect drug-resistant mutation (6) in areas lacking real-time PCR or pyrosequencing capabilities.
