Flagged antibody catalogs

A one-row-per-product view of the 2026 antibody validation-image audit: which catalog numbers have at least one problematic validation image on the vendor's own product page.

Source and credit

Derived from Richardson, R. & David, S. (2026), "Problematic images in vendor antibody verification data", Zenodo, version 260825, published 25 August 2026, DOI 10.5281/zenodo.22090940, licensed CC BY 4.0.

The source audit documents 18,943 problematic images across 17,495 products at 16 vendors. This file is a derived, one-row-per-product summary of the public spreadsheet (260825_catch_all_spreadsheet.csv) from that record. Credit for the underlying identification and annotation belongs to the original authors and the contributors named in the source spreadsheet. This derived file is not affiliated with or endorsed by them.

Columns

column	meaning
catalog_number	vendor catalog number of the affected product
vendor	vendor selling the product
product_title	product title as it appears in the vendor's catalog
flagged_images	number of problematic validation images recorded for this product
first_identified	date the first of those images was identified/annotated
product_link	URL of the vendor's product page
sample_issue	one representative finding for the product, trimmed to 300 chars

Catalog numbers in the source snapshot are unique across vendors (no collisions).

What a flag means

A flag means the vendor's own validation image for that product was identified as problematic (duplication, reuse across clones, apparent manipulation). It is not a claim about the antibody's performance, and not a comment on any paper that used the product. Absence from this list means only that the product is not in the 25 August 2026 snapshot.
