Reproducibility: Standardize antibodies used in research

Open access
Bradbury, Andrew, Plückthun, Andreas·2015·Nature

Abstract

To save millions of dollars and dramatically improve reproducibility, protein-binding reagents must be defined by their sequences and produced as recombinant proteins, say Andrew Bradbury, Andreas Plückthun and 110 co-signatories.

  • 77-90% of biomedical experiments are not reproducible.

    “This observation has been followed by a number of additional reports, the summary of which is, in essence, that 77-90% of biomedical experiments are not reproducible [14-17].”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [14]

    The opening section (page unavailable) reports that a study replicated results from only 6 of 53 landmark preclinical studies—about 89% were not replicated. That supports a figure within the claimed range, but the paper does not give the 77% figure or establish that 77–90% of biomedical experiments generally are not reproducible. (LLM, conf=0.88)

  • Sequence-defined or recombinant products can improve traceability and manufacturing consistency relative to reagents purified directly from animal tissues or biological fluids, which are often chemically undefined.

    “Sequence-defined or recombinant products can improve traceability and manufacturing consistency relative to reagents purified directly from animal tissues or biological fluids, which are often chemically undefined (Bradbury and Plückthun, 2015).”

    From Challenges and solutions in transitioning to animal-free standards: a comprehensive analysis of components in human cell-based developmental neurotoxicity assays (2026) · cites this paper as Bradbury and Plückthun, 2015

    The “TWO STEPS” section says sequence-defined, recombinant antibodies would let researchers use the same binding reagents under the same conditions. “WILDLY VARIABLE” describes animal-serum-derived polyclonal antibodies as mixtures whose functionality varies between batches. The paper supports this comparison for antibodies, but does not establish it for products purified from animal tissues or biological fluids generally, or describe those products as chemically undefined. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Antibodies have limitations including batch-to-batch variation, high production cost, poor chemical stability, and lack of proteoform-specific epitope recognition, which contribute to reproducibility issues.

    “However, antibodies possess many inherent limitations: batch-to-batch variation, high cost of production, poor chemical stability, and lack of proteoform-specific epitope recognition that collectively contribute to reproducibility issues [62–64].”
  • Antibody-based platforms suffer from significant limitations including batch-to-batch variability, high cost of antibody production, and relatively low chemical stability.

    “However, antibody-based platforms suffer from significant limitations including the batch-to-batch variability, high cost of the antibody production, and relatively low chemical stability14,15.”
  • These NPs can serve as replacements to conventional immuno-based techniques to overcome antibody-related limitations in cTnI immunoassays and potentially address the current reproducibility crisis caused by antibodies in general.

    “Thus, these NPs can serve as replacements to conventional immuno-based techniques to overcome the antibody-related limitations in cTnI immunoassays and potentially address the current reproducibility crisis caused by antibodies in general14–16,51,53.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
