Hi Cassidy,
Terrific article! Any chance I could trade emails with someone in your QA Lab familiar with the R5 ELISA testing? It has become an issue of interest to us recently; we would like to learn a little bit about the testing protocol to explore the possibility of performing the assay in-house. If it would be possible to ask a few general questions I’d be grateful!
Cheers,
Jaime Schier
