Protocol for mpox virus inactivation in containment level 3 for safe handling of animal samples
Bibliographic record
Abstract
High biocontainment is required to handle infectious mpox virus (MPXV) specimens, which can hinder research and diagnostic efforts during outbreaks. Here, we present a protocol for inactivating MPXV-contaminated animal samples using commercial lysis buffers. We describe steps for virus propagation and quantification and MPXV inactivation. We then detail procedures for validating the inactivation using a cell-based technique and qPCR. This protocol provides a framework for safely managing MPXV in lower-containment laboratories, facilitating downstream applications and improved outbreak management. • Guidelines for collecting animal samples from CL2 agriculture and spiking with MPXV • Steps to test DNA/RNA extraction kits for their effectiveness in inactivating MPXV • Guidance for inactivation that preserves nucleic acids for downstream applications • Procedure to confirm virus inactivation using cell infection assays and qPCR Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
