Initiatives such as YCharOS test commercial antibodies against knockout cell lines and publish the results, finding that a large fraction of antibodies for a given target fail. A requirement that papers cite knockout- or knockdown-validated antibodies (with the validation record) for key claims, and funder support for a public validation programme covering the most-used cancer targets, would remove a pervasive source of error.","asOf":"2026-09-08","links":[{"label":"YCharOS","url":"https://ycharos.com/"}],"tags":[],"related":["hpa","idea-tr2-reagent-lot-ledger"],"cancers":[],"sections":[],"technologies":["histopathology-ihc"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-reproducibility"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Papers using validated antibodies will show higher replication rates than those using unvalidated ones, and the requirement will shift the market towards validated reagents within three years.","rationale":"Independent knockout-based validation is decisive and increasingly cheap; the barrier is that journals do not require it and vendors do not publish it.","test":"Two journals require validation records for key antibodies; measure compliance and downstream replication in a sample of papers.","maturity":"early-clinical","actor":"policy","cost":"small","horizonYears":2},"route":"/ideas/idea-tr2-antibody-validation-mandate/","neighbours":{"collection":[{"id":"hpa","kind":"collection","name":"Human Protein Atlas","route":"/collections/hpa/"}],"idea":[{"id":"idea-tr2-reagent-lot-ledger","kind":"idea","name":"Barcode every reagent lot so batch effects can be traced across experiments and labs","route":"/ideas/idea-tr2-reagent-lot-ledger/"}],"technology":[{"id":"histopathology-ihc","kind":"technology","name":"Histopathology & immunohistochemistry","route":"/technologies/histopathology-ihc/"}],"bottleneck":[{"id":"b-reproducibility","kind":"bottleneck","name":"Preclinical results do not reproduce","route":"/bottlenecks/b-reproducibility/"}]}}
