Single-Dose Assay Technique for Variola Virus [PDF]
Applied Microbiology, 1964 A biological assay for variola virus was needed that would (i) require a minimum of time and (ii) have acceptable precision. Preliminary titrations made in 11-day-old embryonated eggs and in suckling mice (6 to 24 hr of age) demonstrated a linear relationship between the concentration of variola virus injected and the mean reciprocal time to death (MTD)

MedComm, Volume 7, Issue 7, July 2026.High‐affinity monoclonal antibodies (mAbs) targeting the MPXV EEV protein A35R were rapidly isolated using mRNA‐LNP vaccination and the Beacon single‐cell sorting Optofluidic platform, followed by functional profiling. One mAb, 17H1, potently neutralized authentic MPXV and conferred complete protection in vivo.
