WebJan 18, 2024 · Introduction. Tests to evaluate SARS-CoV-2 immunity are need as vaccine responses and/or protection from prior infection can wane over time [].One surrogate of SARS-CoV-2 immunity is serum viral neutralizing antibodies, which are easy to access (venipuncture) and purify (centrifugation) and are stable if kept sterile and frozen … WebTo address this need, we developed and validated an Affinity Capture Elution (ACE)-AGL assay to detect anti-drug and anti-PEG antibodies. In this assay, which we call ACE-AGL, …
