Editorial commentary

Authentication is one pillar of the reproducibility-policy" class="text-primary underline-offset-2 hover:underline" data-autolinked="true" title="NIH Rigor and Reproducibility policy — CASRAI Dictionary">NIH Rigor and Reproducibility policy. For cell lines, STR profiling against the RRID database; for antibodies, validation against orthogonal reagents and registered RRIDs; for animal strains, genotype confirmation. RRIDs (Research Resource Identifiers) are persistent identifiers that make resource provenance machine-tractable.
